Abstract

QWIPs are renowned for unmatched image uniformity and stability. Still, in popular belief they are often associated with only stationary platforms due to low operating temperature and quantum efficiency. Challenging this myth, we demonstrate the performance of VLWIR QWIP in such demanding applications as handheld camera for gas detection and microsatellite for remote sensing. In the former, NETD of <25 mK is routinely achieved on 15 μm pitch sensor (target 30 C, 30 Hz frame rate, F/1.2, 10.5 μm peak absorption) consuming <9 W. In the latter, the 30 μm pitch array has two IR channels (10 and 10.8 μm) employing monolithically integrated bandpass filters. IDDCA delivers NETD <50 mK for 2 ms integration time (17 °C target, F/1.2) consuming 10 W. It comprises technology demonstrator for evaluating the use of microsatellites for precise temperature monitoring in Earth Observation applications. Stability of its non-uniformity correction, which is paramount for space-born applications, is also demonstrated.
