Project Description

Spectrally-Tunable Infrared Camera Based on Highly-Sensitive Quantum Well Infrared Photodetectors, Phase II
We propose to develop a SPECTRALLY-TUNABLE INFRARED CAMERA based on quantum well infrared photodetector (QWIP) focal plane array (FPA) technology. This will build on the handheld QWIP camera we DELIVERED to NASA in Phase 1 which featured a 320x256 QWIP FPA with fixed spectral response, as proof of this novel sensor technology. Phase 2 will broaden spectral coverage (~ 6 - 12 microns), expand array format to 640x512 (for wider field-of-view), shrink pixel pitch (for higher image spatial resolution), and incorporate a cooled filter wheel with 6 to 8 spectral bands. We will integrate the FPA with dewar/cooler/electronics/optics and deliver the resulting wideband camera to NASA for spectroscopic/imaging studies in this spectral range More »
