1.319μm连续YAG激光束对可见光面阵CCD系统的干扰研究

Study of disturance to visible-light array CCD detectors irradiated by 1.319μm CW YAG laser

利用1.319μm连续钇铝石榴石激光对可见光面阵CCD系统进行干扰实验,分析了该CCD系统发生干扰饱和的原因,计算了1.319μm激光辐照面阵可见光CCD的干扰饱和阈值,利用实验数据在定量上验证了计算结果。当像面上激光功率密度达到102W/cm2量级时,CCD出现饱和串音,达到103W/cm2量级时,出现全屏饱和。

The disturance experiment of array CCD detectors is represented in this paper. In the experiment the visiblelight array CCD detector are irradiated by 1.319μm CW YAG laser. The disturbance saturation reason of CCD detector is analyzed and the saturation threshold is measured. It can be concluded that visiblelight array CCD detector could be effectively disturbed by 1.319μm CW YAG laser from the experiment. When the laser intensity on imaging plane reachs the level of 102W/cm2 and 103W/cm2, the CCD camera appears line saturation and full screen saturation.
