Laser Projector Design Guide

Hi Guys and Gals,

I just wanted to keep you up to date on some cool laser, science and technology news that I thought might interest you.

1. The Allosphere is a huge sphere that allows Scientists to visualize in 3D the data sets being studied. High resolution projectors and audio all powered by a super computer. Imagine standing on the viewing deck with your design team working on a multi-disciplinary project that spans nanotechnology, quantum mechanics, engineering, microscopy, biology, attosecond laser science, metrology and holography to solve complex problems. It reminds me somewhat of the holodeck from Star Trek. This would be a fantastic environment to work in and a great movie set. It looks like it’s straight out of a science fiction movie.

2. True 3D display using high power pulsed laser. Now this is cool. This is true 3D Imagery without a viewing screen. They use a high power laser to Ionize the atmosphere in animated patterns. The plasma generated by the focussed laser beam is visible and extraordinary. I can see that this would be a dangerous display area to the public as the power levels required to Ionize the atmosphere are high enough to burn holes in flesh, start fires, and actually vaporize material in the path of those highly focussed laser beams.

Bono , lead singer from U2 is now wearing a flashy laser jacket to garner attention of fans in the nose bleed seats armed with binoculars. See the weblink and picture here
With literally hundreds of laser pointers sewn into this jacket, rabid fans can always keep track of Bono’s movements across the stage. As a matter of safety, Bono and the band members should be wearing laser safety glasses in case some annoying unwanted reflections should bounce off stage equipment and momentarily disrupt another players vision. I’m sure the laser pointers emit legal laser power levels but whose to say. You be the judge of weather you think it’s cool , or not.

To make an analogy on how attosecond science works, think of how a camera captures a

snapshot of an object in motion over time. To increase the details, a high speed strobe 

and a high speed camera can be used to freeze even finer moments in time. The shorter the

light pulse, the more details you can capture.You have probably seen high speed Images of a

humming bird hovering to eat nectar from a flower or a bullet leaving the barrel of a gun

and thought that was amazing. Those details were captured in the millisecond and microsecond

time frames. As units of time shrink , we go from milliseconds, to microseconds, to

nanoseconds, to picoseconds, to femtoseconds, to attoseconds and eventually zeptoseconds.

Each step shrinks to one thousand times smaller time intervals that seem infinitely small.

An attosecond is very short, a billionth of a billionth, of a second. That's 10 to the minus

18th power or 0.000000000000000001 of a second.

Physicists who study atomic motion have determined that the  oscillation of an

electron orbiting a hydrogen atom moves from one side of the atom to the other every 24

attoseconds. The shortest laser pulse generated to date has been 50 attoseconds which

can freeze the action of an electron in motion around an atom. Using pulsed ultra-fast table top

Infra-red lasers , sophisticated electro-optical setups, vacuum chambers,etc, one can pump

and probe molecules to better understand the fundamental physics of chemistry and atomic

forces. In order to resolve finer details and see smaller objects like molecules and atoms

lasers of shorter wavelength have to be used. Shorter wavelength lasers like ultra-violet

and free-electron X-ray lasers are planned as the next generation of lasers used to gain a

better insight of quantum physics and the forces that ultimately bond everything together.

Canada is playing a major role in leading attosecond science research. The newly opened

"Joint Laboratory for Attosecond Science" is located in Ottawa, Canada and the Director is Paul

Corkrum. Mr. Corkrum is a pioneering researcher in Attosecond science , being a laser and

plasma physicist with Canada’s National Research Council and the University of Ottawa. The Joint

Laboratory for Attosecond Science will be the new home of Canada's fastest X-ray laser at 80 million

pulses per second. The science allowed by ultrafast lasers in the attosecond regime will shed new

light on understanding chemistry on the molecular and atomic level. 

Research at the Joint Laboratory for Attosecond Science may lead to scientific breakthroughs 

in health care,diagnostic medicine,quantum computing,nanotechnology,environmental science and energy.

You never know what you might discover, depending on how far down the rabbit hole you go.

Marvels and mysteries are lying in wait, yet to be revealed.

I have written an e-book titled " RGB Laser Projector Design Guide "
which can be purchased at my website http://www.sniffinfo.com

Amazon recently discontinued the sale of Macmillan titles. Macmillan considered as among the top 6 publishers across the globe. Amazon decided to resort to this action because of a disagreement on the consumer's price for Amazon Kindle and ebook users. According to a notice at Amazon.com, the Kindle Team wrote that they might eventually have to accept the publisher's terms which will mean more costlier Macmillan ebook prices, because they would like to give the Kindle owner the option. Macmillan's titles will range from 5.99 dollars to 14.99 dollars.

The Macmillan group claims that they may actually make less money while Amazon makes more using the digital agent model. The retailer (Amazon) will receive 30% cut from the ebook sales. The physical book market has followed an agency model that has provided considerable gains to all involved, and Macmillan states that the digital market needs a standard to follow as well.

It can't be denied that the publisher, retailer, author and/or illustrator is in business to make money. This monopoly, however, will hurt the consumer in the long run.

Amazon's removal of Macmillan titles is to show their protest of the higher cost, and according to Macmillan's CEO, the disagreement is about the long term market. Obviously the retailer and publisher have diverse view points. Amazon hopes that other publishers won't follow Macmillan's move. But since it is obviously for their benefit,  what would hold other publishers back?

If we take a look at the tangible book market, a consumer who wants to purchase the latest and best hard cover books is going to do so. If the desire can be tamed, then they may wait for the price to take a bit of a dive. The issue is, why should it be any different for the digital book market?

A boycott against Macmillan might be appropriate, however, would it really last? Once a reader is tempted by the most current title from one of Macmillan's exciting writers, the cost doesn't have much weight any longer.

Individuals will continue to pay money for what makes them happy. The simple joys of reading a book has become convenient and so accessible with the use of the ebook reader technology. This alone is enticing, and when you add a new Macmillan title, reading enthusiast will take the bait. We haven't been successful in fighting the urge when it's time for an interesting read.

If you’re a regular Internet user, then chances are that you probably have a Facebook account. The question “are you on Facebook?” is on the tongue of everyone who wants to get in contact with each other. Facebook has become the social networking site of choice, and therefore, it is expected that anyone who is active online will be a part of this site. One’s Facebook profile can be a window into interactions with other people. How can this help marketers like you? This means there is a whole group of people on Facebook just waiting to hear about your site and products. Learn about new SEO software in the market called linkdozer.

No matter where you are, social networking is a viable way to communicate. Despite the Internet’s ability to allow people to interact in differing ways, none of these other methods seemed to have the effect that social networking has on creating connections between people. The largest and most popular of the entries into the new social networking phenomenon has to be Facebook. These days, it seems that people don’t really have an online identity unless they’re Facebook members.

{On a daily basis people log on to Facebook to socialize and encounter new people, get in touch with old acquaintances, and to pass their free time with games and blogging. Are you thinking what I’m thinking? “Wow, is this a venue for my product? Could people on Facebook be interested in my company’s services?” It sure is! There has been an explosion of advertising and marketing efforts that are initiated on Facebook as the industry gets a grasp on the reach of the platform. And since Facebook has millions of users with a huge range of interests, it’s a virtual goldmine for online marketing. in this article you’ll get suggestions for the best ways to use Facebook as a marketing tool.}

{It is simple to use Facebook to advertise your company by utilizing their Social Ads. Social Ads on Facebook are similar to Google Adwords but there are some important differences. It’s the simplest way to advertise on Facebook and the whole system is quite easy to understand implement. You will be able to direct your company’s advertisements to a particular geographical region, age division, or interest. This will prevent your time and money being wasted by traffic that would have no real interest in your product or service. Of course, the more people who click on your advertisement, the more money you will make, and the better clients you will receive.}

You can also add a picture along with your ad if you want. This really creates a momentous impact, as your ad will jump out to your audience and garnish more attention. Make sure you pay attention to what your advertisement says, since this will make all the difference. It’s advisable to hire someone to write your ad copy if you cannot do it effectively yourself. Don’t forget to make an effective design also. Without any doubt link dozer can help you with search engine optimization.

Social Ads is a popular way to advertise on Facebook, but it’s not the only way. You also have the option to create interest groups/pages. It is a virtual viral phenomenon for Facebook users to add pages that they are fans of, or join groups for which they hold an interest. You can take advantage of this and tailor your marketing efforts around it. Simply develop a Facebook page or group that focuses on your company. Make sure to include a concise description of what you do and what your products are. Keep it relatively short. Influence others to become a fan of your business or join your company’s Facebook group. You will be able to send invitations to your company’s group, but if you choose to develop a page instead, you won’t be able to invite users to become fans. In this case, you will be able to direct users to your page through alternative marketing techniques. But whether you make a personal or business page you will be thoroughly thrilled with the results of your efforts. It is all your choice of what to do.

Unlike other social media, Facebook is considered to be a more business-oriented resource because of the tools and opportunities it offers. If you use it right, Facebook can really help your business and assist in marketing your products and services to a fresh customer base. It will require some trial and error, but keep trying and you will find the Facebook method that will be just right for you and will bring you the success that you want.

Every time you turn on the television you see promotions on how you can make money online is sweeping the nation. People need to have something to fall back on with the national economy being what it is today. Many civil service jobs that were sought by many for job security are not being eliminated because of budget cuts and newer technology.

The best way to sell something is to have a good understanding of it. When choosing what you want to sell make sure you have used it and love it. You can’t be a good salesman if you can’t endorse the product. You could research what the best selling product is on the Internet for a home business but that is time consuming and everyone else is probably thinking the same thing.

Something that does not really require knowledge of, but a love of, is books. People who love to read will keep their books forever but is that really necessary. The classics are definitely keepers. And some of the how-to books like the best gardening book whose information is timeless should also be kept for reference.

If you want to be lazy you can sell your books at online book service websites. You just enter the ISBN number on their website and they take care of everything else. They will list the book and then when it sells you will be notified. That is good enough for some people but I like sales transactions to be a little more personable.

Building your own website and listing your books would be much more rewarding. Writing up brief descriptions of each book would give you a greater sense of satisfaction knowing that you personally contributed to the sale of the books. Of course, some are not going to need descriptions. What more would you need to write about a book titled ‘Best Golf Instruction Book‘?

You could personalize your website to make it inviting to come back to. Include an online chat where people could request certain books. Maybe other people in the chat room would know how to get those books so you could all help each other to get the books that people wanted. Because really a business should try to give the people what they want. If you don’t have what they are looking for help them to find it. Customer satisfaction always brings them back.

Obviously this is not advice to get rich quick. But you’ll make new friends and you will be doing the public a service that most businesses have forgotten about. You’ll be having fun and you will be networking which is a great doorway to new opportunities. Another plus of having your own business is that it’s a tax write-off. Any deductions we can find when doing our taxes is going to be a good thing.

Considering the very strong link that Amazon have with books and reading it’s no surprise that the Amazon Kindle reader has proved itself to be a very good fit for Amazon’s business model. During 2009, the market for e-book readers really took off. The Amazon Kindle must be given the credit for much of that, both the Kindle 2 and the Kindle DX, generated a great deal of publicity and helped to develop the e-book market.

At the moment the Kindle reader is Amazon’s number one selling item. It enjoys a 60% share of the US e-book reader market - Sony takes second place with 35%. Both the Kindle 2 and DX model are now on sale in over 100 countries worldwide. There are a lot of new e-book readers, from a variety of different manufacturers, on the market now. Nevertheless, the Kindle still retains the market leader position.

The fact that almost every new reader which shows any promise is immediately christened the “Kindle killer” is a backhanded compliment to Amazon. Amazon has responded to the increased competition level by reducing the price of the Kindle 2 by $100 to $259. The price of the DX model is currently and changed, but the recent launch of the Apple iPad may mean that Amazon need to consider reviewing this price in the near future also.

As well as developing the Kindle hardware and expanding into new markets, the choice of Kindle books available on the Amazon website continues to grow. Currently, there are over 420,000 Kindle books to choose from - an average of 500 new titles are added every day.

Unlike the competition, who seem to be concentrating on development of the hardware, Amazon are making advances in a number of different areas. They are modifying prices, producing firmware updates for the current Kindle, growing the size of their available market and constantly adding to the selection of Kindle books available. Amazon is capitalising on their market leadership position and cashing in on a strong Association with books and reading.

It will be very interesting to note what enhancements Amazon decides to incorporate in the next iteration of the Kindle. This will provide a very clear indication of the way in which the e-book reader market is likely to develop in the near future. Different industry watchers are predicting various dates for the next Kindle update. Given that the Kindle 2 is now over a year old it is almost certain that this will take place in 2010. Some time in the last six months of the year is the most likely timescale according to many industry watchers.

Laser pointers have been around since visible red laser diodes have been on the market which means they’re older than most of the teenagers who buy them. You’ve seen them used at sales meetings, flashed around at music festivals, and even heard about them in the news, flash blinding pilots.

Laser pointers are typically made from direct laser diodes or Diode Pumped Solid State ( DPSS ) lasers. Direct diode pointers are available in red or violet (made from Blu-Ray lasers at 405 nm WL “nanometers wavelength”) and direct diode green and blue will likely soon be available thanks to a company called KAAI who developed them primarily for the micro laser projector market.

Red laser pointers are available in a variety of wavelengths such as 635 nm, 650 nm, 660nm, 670 nm.

DPSS laser pointers are typically available at the following wavelengths, (blue) at 473 nm, (green) at 532 nm and (yellow) at 589 nm and (orange) at 593 nm. Since the human eye is most sensitive to the color green with a peak apparent brightness at 555 nm this means all other visible colors appear less bright despite the same optical power level.

There are a few things to consider if you want to buy a DPSS laser pointer. Those are the power level and the way the diodes are driven. What I mean about power levels, is the actual optical power level measured at the operating wavelength. A typical green DPSS laser pointer has several laser wavelengths involved to generate a frequency doubled visible output.

Beware that unless the manufacturer provides good optical filtering to exclude IR radiation, the power you measure at 532 nm might also be from the other 2 IR laser wavelengths. You can actually get cheap laser pointers that output infra-red light (808 nm and 1064 nm) almost 10 to 20% as high as visible light, which can be dangerous and deceiving to someone who thinks they bought a paper burning power house. A good laser pointer design will only leak out about 1% IR radiation.

There are two ways to drive DPSS laser pointers, this can be pulsed (turned on and off at a fixed frequency) or CW constant wave (on constantly). It’s easy to determine if you have a pulsed DPSS laser pointer as you will see a chopped up line if you move the beam quickly across the ceiling. A pulsed laser pointer will make your batteries last longer but may be distracting if you wave it around a lot during presentations. Beware that people with photosensitive epilepsy are susceptible to flickering/pulsing/strobing lights in the range of 5 to 30 cycles per second .

The last concern with laser pointers is the biggest, which is safety due to the ever increasing power output available today. Typically laser pointers are limited to 5 milliwatts but there are manufacturers that seem to cater to clients who want more power ( made in China ) and who provide pointers which are more like flashlights, outputting power levels as high as 500 milliwatts in green or red. It also doesn’t take a rocket scientist to buy a laser diode and build a laser driver to make their own higher than legal laser pointer.

To provide a perspective on power levels, a 5 milliwatt green laser at 532 nm would be enough to dazzle your night adjusted vision and possibly cause an automotive accident at say a hundred feet from the source. In contrast a 500 milliwatt green laser could easily cause permanent damage to your vision, start fires by burning paper or other combustible materials at short range and definitely distract an airline pilot approaching a runway at a distance of a mile or two. Safety is everything when it comes to laser pointers.

Since laser applications are so widespread, we cannot outlaw laser pointers, but rather try to apply better controls over their use and distribution. Lasers are strictly controlled by the Food and Drug Administration, FDA in the United States and other governing bodies associated with countries that manufacture and sell them. The department of the federal Canadian government that regulates laser pointers is called Health Canada which has it’s headquarters located in Ottawa, Ontario.

To be sure, lasers were inspired by science fiction, and laser pointers attract not only trekkies and star wars fans but people from all walks of life. Be it over zealous sports fans wanting to affect the outcome of a home game or granny getting her exercise and cheap entertainment while playing follow the red dot with her pet cats, lasers are everywhere.

E-books are the future and the future is now. The bound format and printed paper of books used to be the only way information was give and received. They were great, you could take them with you and put them on shelves and they do still exist and will continue to for the foreseeable future but the time of the E-book has arrived.

The marketing E-book is a slightly different animal from just an E-book. Marketing E-books contain text, images, links to web pages and navigation controls. The marketing E-book has become a very important part of marketing on the Internet.

With a marketing E-book you can present your story in an effective way and include links to your web sales pages. Your E-book can become your best salesman.

First, your E-book needs to be interesting and informative. It alway has links back to your sales page and to your website.

Next, be sure that you have a prominent section telling readers that they are free to give your E-book away. Let them know that they can post it on their site as a free download, that they can use it as a bonus, and that they can bundle it with other products. This is how we create viral marketing for your products or services. Remember those links back to your site contained in the E-book?

Last but certainly not least before you send your E-book out to the world, double check spelling and grammar and be sure that you have tested every link to verify that it goes where it is supposed to go. Obvious errors will reflect badly on you and will not be of much value to you, it could even by damaging.

Post your E-book to some of the E-book directories. Many would let post a link on their site to your E-book and post it for free.
