考虑到透镜元件的移动和置换,各种双视场普通热成象系统都采用一个红外扫描器和一个望远镜。对RSRE同轴扫描器的结构进行简单的改进,仅用一个单元探测器,就可同时获得双视场。本文概述了此扫描器的设计和改进,并描述了实现这种新原理所需的附加电子组件和光学组件。这种扫描器的扫描象差比许多现有的扫描器都小。本文介绍了1984年8月组装的第一台样机的制作情况,并且讨论了系统设计思想。 Taking into account the movement and displacement of the lens elements, a variety of dual-view normal thermal imaging systems employ an infrared scanner and a telescope. Simple modification of the structure of the RSRE coaxial scanner enables simultaneous dual field of view with just one unit detector. This article outlines the design and improvement of this scanner and describes the additional electronic and optical components required to implement this new principle. This scanner has less scanning aberrations than many existing scanners. This article describes the production of the first prototype assembled in August 1984 and discusses the system design philosophy.
