Paper Abstract

New cold shields for infrared detectors are described, with which the signal-to-noise ratio was considerably improved. The function of two of these cold shields is based upon the use of intermediate images which make it possible to shield off housing radiation at very small incident angles to the optical axis. With these cold shields, the uniformity of the pictures was improved and the formation of undesirable background patterns was successfully eliminated.
