Infrared radiation imager having sub-pixelization and detector interdigitation

摘要

An infrared radiation ("IR") focal plane array ("FPA") imager includes a detector array chip containing pixels having substantially one-hundred percent operability. Each of the pixels contains a plurality of interdigitated sub-detectors, where the sub-detectors are selectively operable to provide for collection of photogenerated minority charges representative of all or substantially all of the IR radiation absorbed by the detector array chip of the FPA imager.
