双通道成像光谱仪共用离轴三反射光学系统的设计
Optical Design of a Dual-channel Imaging Spectrometer Sharing the Off-axis TMA System
摘要
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.关键词
