【摘要】：在开展激光对光电成像系统的干扰实验时,观察到光电探测器上多组圆环条纹并存的现象,并采用对光学系统拆解、测量、建模重构和光线追迹的方法揭示了每一组圆环条纹的产生机理。首先,对实验所用的光学系统进行拆解,测量各个镜片的曲率半径、厚度、通光孔径等几何结构参数,并采用TRACEPRO光线追迹软件建立了该光学系统的理论模型。基于该光学系统模型,追迹大量光线经光学系统传输后在光电探测器上的能量分布,分析每一种能量组分的来源,发现多组圆环条纹的出现是由于不同激光能量组分的干涉效应而产生的,并揭示了产生每组圆环条纹的对应能量组分。文中的研究结果可为激光对光电成像系统的干扰效果评估提供技术支撑。
[Abstract]:In the experiment of laser interference to the photoelectric imaging system, the phenomenon of multiple ring fringes co-existing on the photodetector was observed, and the optical system was disassembled and measured. The method of modeling reconstruction and ray tracing reveals the mechanism of each ring fringe. Firstly, the optical system used in the experiment is disassembled, and the curvature radius and thickness of each lens are measured. The theoretical model of the optical system is established by using the TRACEPRO ray tracing software, based on the optical system model. Tracing the energy distribution of a large amount of light transmitted through the optical system on the photodetector, and analyzing the source of each energy component. It is found that the appearance of multiple ring fringes is due to the interference effect of different laser energy components. The corresponding energy components of each set of circular fringes are revealed. The results in this paper can provide technical support for the evaluation of the laser interference effect on the photoelectric imaging system.
