Optical window design on a spherical shell
-
摘要: 介绍光电系统中球形壳体上光学窗口的设计方法。以红外窗口为例，对常规平面设计方法和UG实体模型方法进行对比。前者采用试凑的方法，后者利用UG实体建模和空间几何转换的方法，得到了光学窗口的正确尺寸和位置,较前者具有直观和理论性强的特点。根据窗口的光学特性和工程实际，确定了窗口的安装固定方式。Abstract: The design of optical window on a spherical shell in electro-optical systems is introduced. The comparison between conventional design and solid modeling by UG is made by an example of IR window. The former adopts the method of iterative trying, and the latter acquires the correct size and location of the optical window from UG solid modeling and space geometry transform, the latter is more visualized and theoretical sound. According to the optical features and engineering limitations, the installation of the optical window is determined.
