摘要
介绍了一种新型的分划板的设计方法 ,该分划板是以液晶板为核心的显示器。将这种分化板置于电视跟踪镜头的主光路中 ,用以显示瞄准光标 ,可取代电视跟踪镜头的辅助光路 ,使镜头的结构得到简化。文中对液晶分化板的构成作了系统的描述 ,分析了研制中的主要技术难点 ,提出了相应的解决办法。
The paper gives a method for designing a new kind of liquid crystal reticule. By placing the reticule in the main optical path of the TV tracking lens, it can not only take the place of the auxiliary optical path in displaying line of sight, but also simplifies the structure of the lens. In addition to describing the structure of the reticule, the paper also proposes some appropriate ways for solving the key technology problems in its development.
