Experimental results of an investigation on lead sulfide detectors show that their parameters remain unchanged when the level of irradiation generated by Q-switched laser pulses is less than 0.32 Jsq cm. Although the results given in this report cover data from a single detector, tests were made on several detectors under the same conditions with similar results. Incident intensities greater than 0.32 Jsq cm produced sufficient damage in the detector to impair its performance. Laboratory tests showed that, for incident radiation intensity greater than 1.63 Jsq cm, the responsivity and detectivity of the detector decreased appreciably. Author
