ANN ARBOR, Mich.—Protecting helicopters in combat from heat-seeking missiles is the goal of new laser technology created at the University of Michigan and Omni Sciences, Inc., which is a U-M spin-off company.

“Battlefield terrain in places like Afghanistan and Iraq can be so rough that our troops have often had to rely on helicopters, and they can be easy targets for enemies with shoulder-launched missiles,” said Mohammed Islam, a professor in the Department of Electrical Engineering and Computer Science.

“Our lasers give off a signal that’s like throwing sand in the eyes of the missile.”

Using inexpensive, off-the-shelf telecommunications fiber optics, Islam is developing sturdy and portable “mid-infrared supercontinuum lasers” that could blind heat-seeking weapons from a distance of 1.8 miles away.

The technology is being commercialized through Islam’s company, Omni Sciences, which has recently received $1 million in grants from the Army and the Defense Advanced Research Projects Agency (DARPA) to build a second-generation prototype. The Army grant is for $730,000 and the DARPA funding is $300,000.

The lasers are promising for helicopter protection because their robust, simple design can withstand shaky helicopter flight and their mid-infrared supercontinuum mode can effectively jam missile sensors.

Most lasers emit light of just wavelength, or color. But supercontinuum lasers give off a focused beam packed with light from a much broader range of wavelengths. Visible-wavelength supercontinuum lasers, for example, discharge tight columns that appear white because they contain light from across the visible spectrum.

Islam’s mid-infrared supercontinuum laser does the equivalent, but it is the first to operate in longer infrared wavelengths that humans can’t see, but can feel as heat. Heat-seeking missiles are designed to home in on the infrared radiation that the helicopter engine emits.

Because this new laser emits such a broad spectrum of infrared light, it can effectively mimic the engine’s electromagnetic signature and confuse any incoming weapons, Islam said.

This new light source has many military applications, Islam says, but it is especially well suited for helicopters.

“The laser-based infrared countermeasures in use now for some aircraft have 84 pieces of moving optics. They couldn’t withstand the shake, rattle and roll of helicopters,” Islam said. “We’ve used good, old-fashioned stuff from your telephone network to build a laser that has no moving parts.”

Omni Sciences, Inc. has licensed Islam’s technology from the University of Michigan. Islam has a financial interest in this company. Wright-Patterson Air Force Base and the Naval Air Command have also funded this research.

digital projector bulb life

With regards to technical breakthroughs there aren’t many things that are more popular than tvs and electronic projectors. In fact, record information shows that the typical American grownup watches over 3 several hours of television each and every day, and that near to 100 % of American families possess a minimum of 1 Tv set. Although this information might seem worrying, a quick look at your personal situation will probably uncover an identical pattern. Whether or not you approve or disapprove from the trend, the reliance on television offers needed that electronics manufacturers provide all of us with dependable gear with which to see our visible press. With regards to tv sets in particular, a large majority of them utilize DLP technology, which stands for Digital Light Processing.
The reason that fraxel treatments is becoming so popular since it’s release is due to its fairly low cost point when compared to additional technologies like Liquid crystal display and plasma. In addition to less average cost, DLP models perform equally well in a number of metrics associated with picture quality. Information indicates that about 50% of all top projector screen tv sets make use of a DLP> light supply, which makes it one of the dominant gamers on the market. Aside from it’s use within the tv arena, DLP lamps will also be popular in digital projection systems. Actually, in conjunction with 3LCD, both technologies make up regarding 95% of the light supply of just about all projectors sold.
While DLP technologies offers certainly given us much better performance at less typical cost, it’s not without it’s reveal associated with issues. One of the most typical issues negatively effecting the actual technologies is lamp life, which is based purely on use. Even though it is difficult to correctly calculate the life of a DLP light, estimates put the average existence among 1000-2000 hours. The reason behind the big variety is a result of the caliber of the lamp, which can vary dramatically between various brands. At the high end of two,000 hours, users associated with DLP lamps can get to replace their own lamps about each and every one.5 years in the event that their own Television viewing habits follow statistical some social norms. Certainly, lower usage would equate to an extended replacement interval.
With regards to replacing your own DLP bulbs it’s important to look for the recommendation of the tv or even digital projector manufacturer. They can give you a summary of bulbs which will work well in your device and they may actually be able to assist you to get a supplier. When they cannot help you then it is simply a matter of hopping on your favorite search results and trying to find your specific

 “BenQ W1000″ 2010-06-15
By Gymane Moody
I’ve owned this projector for a month and a half. It has worked flawlessly with no issues to speak of.

It’s quieter than my Optoma HD65 with a much brighter and vivid picture.

With a little or a lot of patience you can tweak the color and image to what ever floats your boat.

The W1000 has terrific color and depth, along with sharpness I’ve come to really appreciate. This unit does use a 2 times speed color wheel. Those sensitive to RBE may want to look at the HD20 or Vivitek. A LCD projector could be your best bet if you’re very sensitive to RBE. The great thing about amazon is the satisfaction guarantee.

This is a VERY bright projector! At the present time it is the brightest 1080P projector available under 3 grand.

This gives you more leeway for ambient light to be present in the room. You can eat at the dinner table and still enjoy your movie or show without trying to eat in the dark because your image is washed out by the ambient light.

I like the fact this unit has its own speaker. My nephew loves to play Xbox. We just plug the Xbox directly to the projector and off we go! Nothing like playing video games on a large screen. The speaker is plenty loud enough without disturbing others in the home.

I’ve spent many hours tweaking and calibrating the picture. Here’s a few settings that may or may not help you.

I’ve found it to give me the best balance of color, brightness and contrast so far.

These are settings with the projector 14 ft from the screen with lens wide, lamp hrs of 216 and 120 inch Favi matte white high gain screen. Black levels and contrast will deepen as lamp ages. 100 hrs of burn-in will make a difference for the better in skin tones and black levels.
