为研究宽覆盖多光谱相机的激光干扰效应, 利用红、绿、蓝3种波长激光对3通道CCD(3CCD)相机进行饱和干扰实验, 测量得到了不同波长对应3CCD相机不同通道的饱和阈值, 通过研究3CCD相机的工作原理,对一定波长辐照下3CCD不同通道饱和阈值差别进行分析, 并在实验中对比研究了同一功率下, 单波长和多波长耦合的饱和干扰效果,实验结果表明,多波长耦合要优于单波长的干扰效果。

In order to study the laser interference effects of multi-spectral cameras, interference saturation experiments were conducted on a three-channel CCD camera using red, green, and blue lasers. The saturation threshold at different wavelengths was measured for each channel. The difference among saturation thresholds of different channels was analyzed from the operating principle of the camera, and the saturation interference of single-wavelength and multi-wavelength coupling was comparatively studied under the same power. It is found that the coupled multi-wavelength laser has better interference effect than the single-wavelength one.
