摘　　要：针对目前军用光电搜索跟踪瞄准装置电视摄像系统的搜索范围和作用距离不断提高的需求特点,通过对成熟电视摄像系统的分析比较,明确了采用小型化固定焦距多视场的结构形式。基于该研究方向,提出一种采用嵌入组合式的前物镜组的光机结构设计思路,可实现固定焦距多视场电视摄像系统小型化的设计方案。通过光学设计、光机一体化设计,最终设计完成了一种光学变倍超过20倍、光轴稳定、四视场共用2个成像器件的四视场电视摄像系统,可满足现有军用光电搜索跟踪瞄准装置电视摄像系统的需求。Aiming at the increasing demands for the search scope and oprerating distance of current military photoelectric searching and tracking sighting device TV camera system,through analysis and comparison of the mature TV camera system,a research direction using the structure with miniaturized fixed focal length,multi-field of view（FOV）was clearly determined.Based on the research direction,a design idea using embedded modular front lens group optomechanical srtucture was proposed,which can realize the fixed-focal length,multi-FOV TV camera system miniaturization design plan.After optical design and opto-mechanical integration design,a 4-FOV TV camera with large optical zoom range（20）,stable optical axis and 4FOVs sharing 2common imaging devices was finally completed,it can meet the needs of existing military searching and tracking photoelectric sighting device TV camera system.
