摘要
多波段共孔径共焦面光学系统由于具备“一个光学镜头与一个探测器”的性能等效于传统光学系统(两个光学镜头搭配两个探测器)的能力,共口径共焦面成像能够实现视场与目标信息的匹配,为后续各波段信息融合提供前提条件。基于其光学元件数量少、体积小等特点,已经成为多波段光学系统新的研究方向。特别是环形反射式光学系统,凭借其体积小的优势,在枪瞄准镜、导引头、机器视觉等领域占据着重要的位置。本文以多波段共孔径共焦面光学系统发展为主线,分析了多波段共孔径共焦面光学系统的研究现状,全面介绍了多种类型的多波段共孔径共焦面光学系统,讨论了其光学结构特点、光学系统性能,并比较了这几种光学系统的优缺点,供光学设计领域研究人员共同研讨。
Multi-band common aperture confocal surface optical system as a result of'an optical lens and a detector'performance is equivalent to the ability of the traditional optical system(two optical lenses with two detectors).Co-calibre confocal plane imaging enables the matching of the field of view with the target information and provides a prerequisite for the subsequent fusion of information in all bands.Based on its small number of optical components and small size,this system has become a new research direction of multi-band optical system.In particular,the annular multi-reflection optical systems,with their small size,occupy an important position in the fields of gun sights,guide heads,and machine vision.Taking the development of multi-band common aperture confocal surface optical system as the main line,the research status of multi-band optical system is analyzed,and various types of multi-band common aperture confocal surface optical system are comprehensively introduced.The characteristics of the optical structure,optical system performance,and the advantages and disadvantages of these optical systems are discussed and compared,which provide a reference for researchers in the field of optical design.
