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。
In the experiment of interfering with the electro-optical imaging system, we observed the coexistence of multiple annular stripes on the photodetector and revealed that the optical system disassembly, measurement, modeling and reconstruction and ray tracing each A group of ring streak generation mechanism. First, the optical system used in the experiment was disassembled, geometric parameters such as the radius of curvature, thickness and aperture of each lens were measured. The theoretical model of the optical system was established by TRACEPRO ray tracing software. Based on the optical system model, the energy distribution of a large number of light rays traveling through the optical system after tracing the optical detector is traced, and the source of each energy component is analyzed. It is found that the appearance of multiple annular stripes is caused by the different energy components Interference effect, and reveals the corresponding energy components that generate each set of circular stripes. The research results in this paper can provide technical support for the evaluation of the interference effect of the laser on the electro-optical imaging system.
