Abstract
A 9-mu m cutoff 630 x 486 snap-shot quantum well infrared photodetecto r (QWIP) camera has been demonstrated. The performance of this QWIP ca mera is reported including indoor and outdoor imaging. The noise equiv alent differential temperature (NE Delta T) of 36 mK has been achieved at 300 K background with f/2 optics. This is in good agreement with e xpected focal plane array sensitivity due to the practical limitations on charge handling capacity of the multiplexer, read noise, bias volt age, and operating temperature.
