激光干扰CCD规则亮点分布原理研究

激光干扰CCD时光的传输过程的研究, 对激光干扰CCD干扰图像的仿真、干扰效果的分析等具有重要意义。理论分析了考虑探测器表面反射时的激光干扰CCD时光的传输过程。由于透镜的作用, 首先激光会聚焦到探测器表面。聚焦光会被探测器表面反射。由于CCD探测面是网格状分布, 反射光的分布会被这一结构调制。反射后的光经过透镜, 会成像在某些平面上。根据透镜中光的传输计算发现, 因为透镜的傅里叶变换作用, 光阑平面上会出现周期性的亮点分布。由于光阑平面上不透光的部分的反射, 亮点会再次成像在探测器表面上。仿真了亮点被光阑平面上不透光部分的反射后, 经过光阑后面的透镜又成像在探测器上的过程, 得到了规则的周期性的亮点分布。实验结果验证了这一理论。

Abstract

When CCD was jammed by laser, the study of laser transmission was one of the most important parts for the jamming image simulation and jamming effect evaluation. The transmission of laser considering the reflection of the detection plane was studied. First, laser was focused by the lens. Because the detection plane of CCD was gridding-like structure, the focused laser reflected by the plane was modulated. According to the calculation of the laser transmission through the lens, the periodical spots appeared on the aperture plane. The simulation of the transmission proved that after the spots were reflected by the aperture plane, periodical spots image appeared on the detection plane. The experimental result was in accordance with the theory.
