【摘要】：以光电跟踪测量系统可见光镜头为例,通过对镜头进行仿真分析,寻找杂散光斑形成原因,然后进行杂散光抑制设计,并与实际测试结果对比,验证软件分析方法的可靠性。对光学系统建立软件分析模型,确定一次散射路径,对2°~3°内各离轴角分别进行杂散光分析,找出主要杂散光源。与实际光学系统测试结果对比,以确定分析的正确性。仿真分析结果表明:离轴角在2.20°~2.65°之间,杂散光在像面中心形成明显杂散光斑,点源透过率(PST)为2.92×10-4。最后通过修改结构,消除杂散光斑,PST降为3.53×10-5。软件分析得到镜头的杂散光斑及其来源,与实际测试结果一致,验证了软件分析方法的正确性与准确性。
[Abstract]:Taking the visible light lens of photoelectric tracking system as an example, through the simulation analysis of the lens, we find the cause of stray light spot, then design the stray light suppression, and verify the reliability of the software analysis method compared with the actual test results. The software analysis model is established for the optical system, and a scattering path is determined. The stray light analysis is carried out on each off axis angle in 2 degree ~3 degrees, and the main stray light source is found. The results are compared with the actual optical system test results to determine the correctness of the analysis. The simulation results show that the stray light spots in the center of the image surface and the point source transmittance (PST) are 2.92 x 10-4 between 2.20 degree ~2.65 degrees. Finally, the stray light spots were eliminated by modifying the structure, and the PST was reduced to 3.53 * 10-5. The software analysis obtained the stray spot of the lens and its source, which is consistent with the actual test results, and verifies the correctness and accuracy of the software analysis method.
