Abstract
An infrared imaging system based on a high resolution platinum silicide detector has been developed. The detector is a 486 x 640 Schottky Barrier photodiode array with a CCD readout multiplexer. The imaging system includes signal processing electronics to correct the fixed pattern noise and implements a histogram projection algorithm for automatic gain and offset adjustment and dynamic range compression. The perfonnance of the pattern noise correction has been demonstrated to reduce the residual pattern noise below the image shot noise over a scene temperature range of more than 50°C. The effect of optical cmss talk in the imager has been examined. The magnitude of the side lobes has been found to be a factor of about 7 x 10' smaller than the central spot.
