摘要:
提出了一种双通道共用一个主光学的推帚式高光谱成像仪光学系统,该系统由离轴三反射主光学系统、狭缝、准直镜及分色镜、可见近红外光谱仪后光学和短波红外光谱仪后光学组成,设计中采用双通道共用离轴三反射主光学系统,不仅满足了成像仪大视场、宽谱段的要求,而且提高了系统的光学效率,使系统结构更加紧凑,双通道光谱仪均采用棱镜-全息透射光栅-棱镜分光组件分光,实现了宽光谱分光,提高了衍射效率,系统实现光谱范围覆盖450~2500 nm,全视场达23.9?。
Abstract:
This paper presents an optical system for a dual-channel pushbroom hyperspectral imaging spectrometer which shared a main optics. This optical system consists of the main optics, slit, collimator, dichroic mirror and the optical components of VISNIR and SWIR. The two channels sharing off-axis Three-Mirror Anastigmatic (TMA) telescope system is designed, which is not only to meet the requirements of the imager about field of view, wide spectra, but also to improve the optical efficiency and make the system more compact. Prism Grating-Prism (PGP) components are used to achieve a wide spectrum spectrophotometry and high diffraction efficiency, whose response covers the range from 450 to 2500 nm with a 23.9? field of view.
