英文摘要：

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.
