Researchers have developed a low-cost hyperspectral camera that can read detailed vein and skin texture patterns that are unique to each individual.Developed by the University of Washington and Microsoft Research, the HyperCam identified 99% of people it was used on in an informal study.”When you look at a scene with a naked eye or a normal camera, you're mostly seeing colors. You can say, 'Oh, that's a pair of blue pants,'” lead author Mayank Goel said in a statement. Goel is a UW computer science and engineering doctoral student and Microsoft Research graduate fellow. “With a hyperspectral camera, you're looking at the actual material that something is made of. You can see the difference between blue denim and blue cotton.”HyperCam costs roughly $800, but potentially as little as $50 to add to a mobile phone camera.Unlike a typical camera that divides visible light into three bands, this device uses other wavelengths in the electromagnetic spectrum can reveal invisible differences.HyperCam uses the visible and near-infrared parts of the electromagnetic spectrum, illuminating a scene with 17 different wavelengths and generates an image for each.
