弹道相机主要用于测量飞行体的弹道轨迹,也用于校验其它光学电子学靶场测量设备。它属于高精度光学摄影测量设备。其工作基本原理是将被摄运动目标的一系列点象和天空基准恒星象点同时记录于大尺寸的感光底板上,用座标量测仪测量底版上的星象和计算机处理所得到弹道数据。本文讨论此种摄影测量的镜的光学参数选择、设计要求、光学镜头的结构型式和光学设计要点以及各种型式可能做到的水平。
Ballistic cameras are mainly used to measure the ballistic trajectory of a flying body and are also used to verify other optical electronics range measuring equipment. It belongs to high-precision optical photogrammetry equipment. The basic principle of the work is to record a series of point images of the moving target and the sky reference star point simultaneously on a large-size photosensitive bottom plate. The coordinate measuring instrument measures asteroids on the bottom plate and the ballistic data processed by the computer. This article discusses the optical parameters of this photogrammetric measurement, design requirements, structural and optical design considerations of optical lenses, and the possible levels of various types of measurements.
