Abstract
A 9 μm cutoff 640×512 pixel hand-held quantum well IR photodetector (QWIP) camera has been demonstrated wiht excellent imagery. Based on the single pixel test data, a nose equivalent differential temperature (NETD) of 8 mK is expected at 65K operating temperature with f/2 optics at 300K background. This focal plane array has shown backgeround lmiited performance at 72K operating temperature with the same optics and background conditions. In this paper, we discuss the development of this very sensitive long wavelength IR (LWIR) camera based on a GaAs/AlGaAs QWIP focal plane array and its performance in quantum efficiency, NETD, uniformity, and operability.
