摘要

In this paper, we introduce the working principle of dispersion imaging spectrometer, describe the system composition ofimaging spectrometer. Through analysis and comparison, we select the Cerny-Turner for the optical path structure ofspectrometer. Then, we simulate and optimize the initial structure of the optical system of imaging spectrometer by usingoptical design software. At the same time, we use the cylinder reflector with low cost and easy processing and detectionto correct astigmatism. Finally, we designe an optical system of vis-shorter-wave infrared imaging spectrometer with aspectral range of 400~1000nm. The contrast of full-band and full-field MTF of imaging spectrometer at 25lp is better than0.3. After these, we design the mechanical structure of the optical system of the optimized imaging spectrometer by usingthe mechanical structure design software. Then, we use 3D printer to print various structural parts to develope a highresolution imaging spectrometer. Finally, we carried out an experiment by the kunyu river in haidian district, Beijing,which proved that the imaging spectrum technology can be used in the monitoring and research of water pollution andvegetation in rivers and wetlands.
