Abstract :
A 9 μm cutoff 256×256 hand-held quantum well infrared photodetector (QWIP) camera has been demonstrated. Excellent imagery, with a noise equivalent differential temperature (NEΔT) of 26 mK has been achieved. In this paper, the authors discuss the performance of this portable long-wavelength infrared camera in quantum efficiency, NEΔT, minimum resolvable temperature difference (MRTD), uniformity, etc. and its civilian applications
