Abstract

A 9 micrometer cutoff 256 by 256 hand-held quantum well infrared photodetector (QWIP) camera has been demonstrated. Excellent imagery, with a noise equivalent differential temperature (NE(Delta) T) of 26 mK has been achieved. In this paper, we discuss the performance of this portable long- wavelength infrared camera in quantum efficiency, NE(Delta) T, minimum resolvable temperature difference (MRTD), uniformity, etc., and its applications in science, medicine and defense.
