Abstract

Thermal imaging in the 3-5 micrometer band has been reported using Pt-Si detectors in staring mosaic arrays of more than 2000 elements. Excellent imagery has been obtained directly from the arrays without any need for signal processing or image enhancement. The only processing required for display is data reformatting to make the images compatible with standard TV frame rates. The absence of any need for image enhancement is a direct consequence of the excellent uniformity which can be obtained over large areas of the silicon wafer using Pt-Si detectors. Detector uniformities of better than 1/2% over a one centimeter area and extremely low fixed pattern noise in the readout CCD's have allowed image details to be displayed with 1/10°C accuracy.
