Abstract

This paper proposes a technique for estimating the degree of shielding of optoelectronic observation devices with photodetector arrays from radiation sources outside the field. Results are presented for test-stand measurements of a television-type optoelectronic device equipped with a wide-angle objective (2b=76°) and a flared light-shielding blind of rectangular cross section with a field of view of 62°X48°. Quantitative estimates are obtained for the operating efficiency of the light-shielding blind by simulating illumination outside the field of its optical input from a solar-radiation simulator. It is shown that a light-shielding blind of the given design protects the optical system of a device from the disturbing action of out-of-field illumination within 63% of the front hemisphere.
