INSTALLATION OF AUTOMATED MEASUREMENTS multispectral photodetector arrays

摘要

The claimed utility model is intended to measure parameters multispectral photodetector arrays (FPA) of infrared (IR) spectral range from 2 to 14 microns in normal climatic conditions, and can be used for measuring dark current, photocurrent, resistance, current and voltage sensitivity, RMS noise values , photosignal, specific detection sensitivity and threshold radiation power. The installation comprises successively established source of infrared radiation - a black body (1) with a temperature control unit (2), the unit of replaceable diaphragms (3), the apparatus spectral filtering of images (4) comprising a removable nonrearranged interference filter (5) and a blocking filter ( 6) multispectral MFP (7) and interface unit (8) with a working temperature gauge (9), measurement system (10) with the interface board ADC-DAC (11) and a personal computer (12). The utility model provides multispectral measurement parameter MFP with high accuracy, 1 bp f BACKGROUND ZP 1 f ly-2 Fig.
