- Abstract
- The IR array photodetector with the new cold stop is offered. This diaphragm allows to establish a set of irradiation to improve its alignment on array's area and to provide the best signal/noise ratio for the IR array photodetector. The comparison of photo-electric array's parameters with the cold stop and with the cold shields of standard type is executed. The influence of the parasitic background radiation and IC's noise on photo-electric parameters is considered. The advantages of the IR array photodetector with the new cold stop are shown.
