How to use infrared in a sentence?

1. Gene Klager:

   We are developing algorithms for infrared search and track - we have a passive way to detect and track we would then hand off the target location to a countermeasure system.

2. Miles Barr:

   Light absorbing dyes are found all around us. They're in paints, they're in pigments for clothing, and they're even in electronic devices, what we've done is we've engineered those dyes to selectively absorb infrared light and also convert that light into electricity.

3. Alon Gorodetsky:

   There is a lot of flexibility in how one can deploy this material, essentially, by taking the stickers and putting them all over yourself, you could look one way under optical visualization and another way under an active infrared visualization camera.

4. Geoffrey Carter:

   The infrared looks for a flash from a gunshot and the acoustics listens for the bang, so we get the flash and the bang, and then we cue the operator. The accoustics get us very accurate azimuth, or bearing, to the threat. The combination of knowing the speed of light and the speed of sound, we’re able to get the distance in the time of arrival to the threat.

5. John Venable of D.C.-based:

   Any time you have a high flashpoint on the ground, there’s an array out there called the Space-Based Infrared System, and we can detect just about any major launch or explosion on the face of the Earth, but the ability to track those once they actually leave the atmosphere and start their trajectory is complicated by the movement of these vehicles.
