Large format HgCdTe focal plane arrays for dual-band long-wavelength infrared detection

Authors


Abstract

Raytheon Visions Systems (RVS) is furthering its capability to deliver state-of-the-art high performance large format HgCdTe focal plane arrays (FPAs) for dual-band long-wavelength infrared (LWIR) detection. Missile seekers are designed to acquire targets of interest at long ranges and discriminate targets from clutter. The use of dual-band long wavelength infrared detector technology provides the ability for these seekers to combine these operations into the same package with enhanced performance. Increasing the format size of dual-band long-wavelength FPAs and tailoring the detector design for specific long-wavelength bands enables seekers to be designed for increased field-of-view, longer target acquisition ranges, and improved accuracy. This paper will review in further detail the aspects of detector design, MBE wafer growth, wafer fabrication, and detector characterization that are contributing to development and demonstration of high performance large format dual-band LWIR FPAs at RVS.
