摘要:介绍了基于同心结构的Offner成像光谱仪光学系统的工作原理、结构特点及优势,综述了Offner型成像光谱仪在国内外的研究进展。较详细地介绍了国内外目前常用的三种消像差方式,即通过改变光学元件装调结构实现消像差,基于单光栅像差理论的解析方法进行消像差以及通过设计凸面全息光栅来提高光谱图像的分辨率。文中总结了Offner 成像光诺仪存在的关键问题及发展趋势,强调该系统需要解决的间题的是消除系统像差,提高系统光谱分辨率、空间分辨率和对弱信号的探测能力,其发展方向为更高的分辨率和探测能力以及系统的小型化和轻量化。基于对Offner成像光谱仪的研究,文中提出了一种从凸面全息光栅与光谱仪一体化设计的角度进行消像差的思路。

Abstract: The working principle, structure characteristics and advantages of the optical system in an Offner imaging spectrometer are introduced based on a concentric structure. The research and devel-opment of the Offner imaging spectrometer are overviewed. It describes in detail the commonly used three kinds of correction aberration ways, namely by changing optical element adjustable structure to correct the aberration, by aberration theory analysis based on single grating to correct the aberration and by design of a convex holographic grating to improve the resolution of the spectral image. Then, it summarizes the key problems of the Offner imaging spectrometer and emphasizes some of them should be solved in further, such as correction of the system aberration, improvement of spectral reso lution and spatial resolution and enhancement of detecting weak signals. Finally, it points out that the development trend of the system is higher resolution, better detecting capability and more compact structure. Based on the research of the Offner imaging spectrometer, this paper proposes an approach
