New Photodetector Enables NASA’s Thermal Imager
GREENBELT, Md., Aug. 2, 2018 — A compact thermal camera named the Compact Thermal Imager, or CTI, has been developed by NASA using photodetector technology known as strained-layer superlattice, or SLS. NASA's advanced detector technology, a strained-layer superlattice (SLS) detector, will be demonstrated on an upcoming robotic servicing demonstration mission. Courtesy of NASA. The SLS assembly is a large-format detector, measuring nearly 16 in. long and 6 in. tall. It consumes little power, operates at
