A Review of Dyson Optical System in the Measure of Infrared Imaging Spectrum

传统的红外成像光谱仪难以同时实现弱遥感信号下的高信噪比和仪器小型化的要求,基于Dyson同心光学结构的新型遥感红外成像光谱仪具有数值孔径大、信噪比高、结构简单、体积小、重量轻的优点,用于强背景信号下的微弱红外成像光谱信号测量时,可实现传统的红外成像光谱仪难以实现的高信噪比测量。本文概述了Dyson同心光学结构的产生、发展及最新研究动态,重点介绍了Dyson同心光谱仪的原理、研制过程中的难点以及在高性能遥感红外成像光谱测量中的应用,为高性能红外成像光谱仪的研究提供了参考。

It is difficult for the traditional infrared imaging spectrometers to satisfy the requirement of high signal to noise ratio（SNR） and small size simultaneously.The new infrared remote sensing imaging spectrometers based on Dyson concentric optical configuration have the advantages of high aperture,high SNR,simpleness small volume and low weight.The Dyson imaging spectrometers can achieve high SNR,which is difficult for the traditional imaging spectrometers for infrared imaging spectrum.The present review introduces the beginning,the development and the present research of the Dyson imaging spectrometers,especially illustrates the principle of Dyson concentric spectrometer,difficulty during its manufacture and the application in the high-performance infrared remote sensing imaging spectrometers,providing a reference for the high-performance research of infrared remote sensing imaging spectrometers.
