A team of engineers built a system that allowed people to see colors in the infrared spectrum – as long as they were looking through a camera lens.
We can see light with wavelengths in the visible spectrum, a fairly narrow band of color between ultraviolet and infrared rays. But researchers from Tel Aviv University have built a system mounted on a camera that makes it possible to see the colors of infrared light. Reviews on Laser & Photonics. It makes an inexpensive ordinary scientific tool more accessible – to the point where it can be used for either photography or civic science.
The device can be used to visualize gases such as hydrogen, carbon and sodium, each of which glows brightly in infrared rays, the team says. It can also image scenes in nature, which tend to look like other worlds under infrared light.
“[Visible light is] only a small fraction of the electromagnetic spectrum, including radio waves, microwaves, X-rays and more, ”said Tel Avivian physicist Michael Mrejen in a press release. “In each of these parts of the electromagnetic spectrum, there is a lot of information about materials encoded as ̵6;colors’ that have so far been hidden from view.”
Fun and games
In addition to photography and science, the scientists suggest some slightly more efficient uses for their low-cost infrared technology.
“So an environmental monitoring satellite can ‘see’ a pollutant emitted from a factory,” co-author Haim Suchowski said in the statement, “or a spy satellite would see. where the explosives or uranium are being hidden. “
