摘要
响应度R是反映探测器性能的一项重要指标。当光电探测器被激光损伤后,其响应度R将会下降。文中探讨了强激光对光电探测器的损伤机理,对不同功率密度强激光作用下探测器的光谱进行了测量,研究了探测器在强激光辐照下探测器响应度变化规律。对光电对抗以及光电探测器的抗激光损伤研究具有一定的参考价值。
Responsivity is an important factor reflecting the performance of photoelectric detector, responsivity was reduced when the detector was damaged by laser. In this paper, the damage mechanism of detector under laser irradation was analyzed. The spetal responsivity of the detector irradiated by Nd： YAG laser with different power density was measured. And the principle of responsivity of detector irradiated was investigated. The paper has some reference values for the research on electro-optical countermeasure and detector anti-damage for laser .
