| 摘 要： | 针对非成像式激光告警系统的工作特点与要求，提出并设计了一种双片式柱透镜光学结构。对柱面光线追迹以及柱透镜成像进行了深入分析，提出了一种新型像差优化方法，使其在子午方向各个视场的调制传递函数得到最大幅度的优化。此光学系统由两片硒化锌柱透镜组成，满足了1.0~4.0 m 工作波长范围，并且克服了传统单片式柱透镜和柱面反射镜视场通常小于1且聚焦线斑不理想的缺点，其视场达到20，在7lp/mm 空间分辨率条件下，边缘视场子午方向的调制传递函数值优于0.7，达到了非成像式激光告警系统的要求。

| Abstract: | Based on the characteristic of laser warning system with non-imaging imaging mode, a double cylindrical lens system was presented. A new optimization method, based on the ray tracing of cylindrical lens, was introduced in this paper. Traditional single-cylindrical lens and cylindrical reflector systems were limited by FOV, less than 1, and low-quality line spot. This optical system, composed by two ZnSe cylindrical lenses, meets the operating wavelength of 1.0-4.0 m and achieves a 20FOV and the modulation transfer function(MTF) is better than 0.7 at 7 lp/mm on the edge of FOV. This optical system achieves the requirement of laser warning system with non-imaging mode. |
