QWIP chip dual-color and multicolor FPAs for military applications

Quantum Well Infrared Photodetectors (QWIPs) based infrared focal plane arrays (FPAs) are commercially available in the single color. QWIP Technologies, Inc. provides a number of QWIPCHIPTM FPAs available in the single-color, dual-color and even multiple-color, as well as varieties of physical formats in the infrared range. In this paper, we discuss the research and development efforts currently ongoing at QWIP Technologies on dual-color, visible-NIR/LWIR FPAs, and the development of a four-color QWIP-based FPA. These multicolor systems are being developed to meet the needs of a number of military applications including land mine detection. Land mines inhibit the safe movement of troops and produce chaos in countries struggling for socio-economic stability long after the cessation of hostilities. This paper will describe the efforts to develop a near multi-color QWIP sensor for mine detection. The core of the discussion will include highlights of a two-color LWIR QWIP sensor system designed to provide uniform, high spatial resolution, multi-color co-registered imagery and possess negligible spectral cross-talk. Through these efforts, The Defense Advanced Research Projects Agency (DARPA) is completing the development of a visible/infrared mine detection system, which when deployed on an airborne platform, would increase the war fighting effectiveness has sponsored the current developments.
