Abstract
Two-point nonuniformity correction has been realized at Amber Engineering using an analog technique for the correction of pixel offsets and gains in real time. This system has been designed for use with Amber's 128 x 128 focal plane arrays, and a new system based upon similar concepts is being built for Amber's 256 x 256 arrays. The analog circuitry is much smaller and consumes less power than digital circuitry performing the same operations. Better than an order of magnitude reduction in electronics volume as well as power dissipation has been realized using this analog technique as opposed to the digital method while maintaining the same level of performance. Extrapolation of these techniques leads to incorporation of nonuniformity correction on FPAs in a generation of readout devices that will be available in 1992.
