Paper Abstract

The Jet Propulsion Laboratory (JPL) is developing a 512x640-format, dual broadband, Quanum Well Infrared Photodetector (QWIP) focal plane array (FPA) for an imaging interferometer. This is a new type of imaging interferometer which is based on special Fourier-transform spectroscopy, scans interferograms digitally without moving any optical components. It is stable enough to measure fluctuating target signatures from unstable platforms, making it ideal for detecting chemical agents from a remotely piloted aircraft. These static interferometers require large-format FPAs with high uniformity and operability. QWIP technology is ideal for this instrument because it has achieved remarkable success in advancing highly uniform, highly-operability, and large-format multicolor FPAs. The FPA used in the interferometer covers the wavelength from 6-10 μm and 10-15 μm in alternative rows.
