Abstract

The traditional approaches using multiple focal plane arrays (FPAs), filters, beam splitters, cooling circuits etc, complicate system design, reliability and create difficulty in spatial alignment and temporal registration of image at the pixel level. Multiple colors on a single full-resolution FPA will greatly improve spectral discrimination capability at longer ranges. The integrated multicolor infrared FPAs in which a single pixel location is sensitive to two (or three) separate IR spectral bands will be the future generation technology for its use in target acquisition and signature recognition in a wide variety of space and ground based applications. This paper reviews key developments and status of this important technology. Projections and challenges for the continued evolution of this technology are also discussed.
