ABSTRACT:
A method for determining proper operation of a multi-section photo-sensitive detector (10) includes measuring (102) the cathode-anode dark resistance of each section and rejecting the detector (104, 108) if any section measures less than a predetermined value or if the ratio of the dark resistance of any section to the section having the highest dark resistance (106) exceeds a specified level. Each detector is also subjected to anode-to-anode or cathode-to-cathode dark resistance testing for both adjacent (110) and non-adjacent (124) sections, with testing based on comparisons between section pair readings and the sum of the cathode-anode dark resistances of each section in the tested pair (114, 128).
