摘要
为了满足激光武器对光束质量日益增长的需求,提出了一种光学准直系统的设计思路及非球面镜优化方法,并将该方法成功应用于一款激光热灼枪的镜头设计,使该枪可以在更远范围内获得更高质量的准直光束。首先在战技参数分析和光路计算的基础上得到初始结构,而后对其进行非球面优化,并基于ZEMAX对两次仿真结果做出对比分析,数值结果显示优化结构具有显著优势,其非球系数和曲率半径分别为0.584 mm和115.37 mm,光能利用率在使用GB 1316-88减反射膜的情况下可达99.92%。经过公差分析后加工出镜头并与枪体组合进行了木板烧蚀实验,实验与仿真结果吻合度良好,镜头性能的优越性证明了所提出设计及优化方法的可行性与合理性,也为其他领域的类似问题提供了一定的参考价值。
In order to meet the increasing demand for beam quality of laser weapons,a design and aspheric optimization method of optical collimation system was proposed.This method was successfully applied to the lens design of a laser cauterization gun,so that the gun could obtain a higher quality collimating beam in a farther range.First,the initial structure was obtained based on the analysis of tactical and technical parameters and the calculation of the optical path,then the aspherical optimization was performed,the two simulation results were compared and analyzed based on ZEMAX.Numerical results show that the optimized structure has significant advantages.Its aspheric coefficient and curvature radius are 0.584 mm and 115.37 mm respectively,and the light energy utilization rate can reach 99.92%when the GB 1316-88 anti-reflection film is used.After tolerance analysis,the lens was processed and combined with the gun body for a board ablation experiment.The experimental results are in good agreement with the simulation results.The superiority of lens performance proves the feasibility and rationality of the proposed design and optimization method,and also provides a certain reference value for similar problems in other fields.
