Abstract
A system for multispectral imaging and ranging is provided. The system comprises at least one light illumination source, and a focal plane detector array configured to support both passive imaging and active imaging at multiple wavelengths. The focal plane detector array includes a plurality of pixels, wherein each of the pixels comprises a plurality of detectors. The detectors are configured to collect passive light to support passive imaging; collect retro-reflected light, transmitted by the at least one light illumination source, to support active illuminated imaging; and collect retro-reflected light, transmitted by the at least one light illumination source, to support active illuminated ranging.
