Abstract

In this paper, an experimental system for detecting the damage degree of the imaging optical system by using the cat's eye echo is established. The change mechanism of peak power of cat's eye echo is analyzed under different irradiation time. The relationship between the peak power of the echo and the damage degree of the CCD are established accordingly. The study found that the peak power of the cat's eyes echoes decrease dramatically, then increase significantly, then drop again, then increase again and decrease finally with the increase of the degree of damage of the CCD according to the damage order. In practical application, it is possible to judge the damage state of the enemies optoelectronic imaging equipment according to this rule.
