A team of computer science and electric engineers from the University of Washington (Seattle, WA, USA; www.washington.edu) and Microsoft Research (Redmond, WA, USA; www.research.microsoft.com) have developed an affordable hyperspectral camera that uses visible and near-infrared light.
This system costs approximately $800 and is based on a FL3-U3-13Y3M-C USB 3.1 camera. The camera features a 1.3 MPixel ON Semiconductor (Phoenix, AZ, USA; www.onsemi.com) VITA1300 CMOS image sensor that can achieve frame rate up to 150fps and is sensitive from 350-1080 nm with peak quantum efficiency at 560 nm. The camera uses 17 different spectral bands that are created using narrow-band, off-the-shelf LEDs configured in a ring arrangement. The wavelengths for these LEDs vary from 450 to 990 nm, and were selected to cover the camera's sensitivity range.
