Therefore, it is not possible for any F-35 schedule to include a video data link or infrared pointer at this point.
Unlike humans, it can watch for days, even years, watch an entire city, zoom in close, use heat sensors and infrared.
infrared light does not have a color which means it cannot be seen by the human eye.
Ultrasound and infrared light help penetrate the serum, said to protect skin from sun and other damaging free radicals.
Helicopters equipped with infrared equipment flew over the area.
You rig this thing on the camera, which is loaded with infrared film.
The infrared detector gave him no range information, of course.
He flashed the infrared light, saw that they were still heading properly, and cut it off again.
Their vision range is from just within the visible red on into the infrared.
The Hindu boy didn't know about the infrared camera, unless the others had explained it to him.
infrared in·fra·red (ĭn'frə-rěd')
Of or relating to the range of invisible radiation wavelengths from about 750 nanometers, just longer than red in the visible spectrum, to 1 millimeter, on the border of the microwave region.
Generating, using, or sensitive to infrared radiation.
Relating to the invisible part of the electromagnetic spectrum with wavelengths longer than those of visible red light but shorter than those of microwaves. See more at electromagnetic spectrum.
Our Living Language : In 1800 the astronomer Sir William Herschel discovered infrared light while exploring the relationship between heat and light. Herschel used a prism to split a beam of sunlight into a spectrum and then placed a thermometer in each of the bands of light. When he placed the thermometer just outside the red band, where there was no visible color, the temperature rose, as if light were shining on the thermometer. Further experiment showed that this invisible radiation behaved like visible light in many ways; for example, it could be reflected by a mirror. Infrared radiation is simply electromagnetic radiation with a lower frequency than visible light, having longer wavelengths of 0.7 micrometer to 1 millimeter. Ultraviolet radiation, like infrared radiation, lies just outside the visible part of the spectrum, but with higher frequencies; some animals, such as bees, are capable of seeing such radiation. Both infrared and ultraviolet radiation are often referred to as forms of light, though they cannot be seen by human beings. Heat energy is often transferred in the form of infrared radiation, which is given off from an object as a result of molecular collisions within it. Molecules typically have a characteristic infrared absorption spectrum, and infrared spectroscopy is a common technique for identifying the molecular structure of substances. Astronomers similarly analyze the infrared radiation emitted by celestial bodies to determine their temperature and composition.
