摘要
以空间非合作目标探测为背景,提出了一种折衍射混合中波红外双视场光学系统的设计。与连续变焦光学系统相比,红外双视场光学系统具有结构简单、装调容易、能够实现快速视场切换等特点。设计了一款轻量化、结构紧凑的折衍射混合红外双视场光学系统,系统采用二次成像结构,通过变焦组的轴向移动实现双视场,工作波段为3.7~4.8 μm,由7片透镜组成,可实现160 mm/40 mm两档变焦,满足100%冷光阑效率,具有结构紧凑、像质高和成本低等优点。
Abstract
Based on the spatial non-cooperative target detectors, a design of hybrid diffractive/refractive dual-field-of-view middle-wave infrared optical system is put forward. Compared with the continuous zoom optical system, infrared dual-field-of-view optical system has many advantages, such as simple structure, easy fixing, quick switching and so on. A compact and lightweight infrared dual-field-of-view hybrid diffractive/refractive optical system is designed. The zoom system has intermediate image plane and the zoom group is moved through the optical axis to implement dual-field-of-view. The system consists of only seven lenses, and can realize 160 mm/40 mm dual-field-of-view at the spectrum region of 3.7~4.8 μm, which can obtain the cold shield efficiency of 100%.The design result shows that the system has the advantages of compact structure, high image quality and low price.
