MULTI-SPECTRAL INFRARED CAMERA COVERING WAVELENGTHS FROM 1 TO 16 MICRONS

QmagiQ proposes to develop and deliver to NASA a multi-spectral infrared camera covering a broad range of wavelengths from 1 micron to 16 microns.nbsp; A key feature is a broadband high-quantum-efficiency strained layer superlattice focal plane array (SLS FPA) with spectral filters integrated directly on the FPA ndash; a design that allows the camera to be very compact.nbsp; The spectroscopic information provided by the filters will be useful in detecting and identifying a variety of hot and cold targets at great distances and inferring their chemistry.In Phase I, we developed a SLS FPA with cutoff wavelength exceeding 14 microns, quantum efficiency of 20-30%, operating temperature of 68K, and excellent array uniformity, pixel operability and image stability.nbsp; In Phase II, we will extend cutoff wavelength past 16 microns, expand array format to 1Kx1K, integrate filters onto the FPA, and package the FPA/filter assembly into a compact camera equipped for remote stand-alone operation.The camera will be valuable to NASA for space telescopes (where its much higher operating temperature compared to Si BIB detectors offers longer operating life) and for Earth and Planetary Science Decadal Survey priorities like infrared sounding.nbsp; In addition to detecting, tracking and chemically analyzing fires, a drone equipped with such a multi-spectral camera can also be used to monitor and analyze vegetation, forests, crops, industrial gas leaks, and pollution.
