摘　　要：为了对比研究激光对可见光CCD的干扰效果，采用532nm，808nm和1064nm波长的激光对同一可见光CCD进行了干扰实验。结果表明，3种波长的激光对CCD都有一定的干扰效果，由于干扰波长、干扰功率、工作方式等不一样，干扰效果也存在差异。对于脉冲式激光器，532nm激光比1064nm激光具有更低的光饱和阈值；当各波长激光输出达到一定功率时，CCD会出现饱和串音的现象。此干扰实验为更好干扰CCD成像系统提供了一定的实验依据。
To study the laser jamming of CCD comparatively , three lasers at wavelengths of 532nm, 808nm and 1064nm were adopted in the jamming experiments .The experiments results reveal that the jamming of three lasers to CCD is effective .However , the jamming effect is different because of the difference of the jamming wavelength , the power and the working mode.For pulsed lasers, 532nm laser has the lower light saturation threshold than 1064nm laser.When the output laser power reaches a certain value , the saturation crosstalk phenomenon occurs in a CCD . It provides an experimental basis for better jamming against CCD imaging systems .
