Abstract

In the thesis we introduce the basic design of the solar multi-spectrum telescope and imaging system. The whole system consists of Cassegrainian reflecting telescope, light-splitting system, light-filtering system, photo emissive detector group, calibration spectroscopy system and solar UV light source Simulated in order to image solar UV radiation, visible light and infrared band respectively and get video. The catadioptric parts of our system guarantee to image the three spectrums at the same time. There are turntable filter group before the detectors to achieve visible and ultraviolet band of more specific band imaging. Spectrophotometry system uses germanium spectroscope and spectrophotometry plane mirror to let the infrared and visible light through. And we coat spectroscope and spectrophotometry plane mirror UV-reflective film to achieve UV reflectance spectrophotometry. At last, we get real-time video image in three specific spectrums in a coaxial optical system. Since working in space for some time, the external factors will lead to our system to produce the spectrum of radiation drift. Therefore we add radiation calibration spectra to the system which provide a standard spectral radiation parameters to provide the detected result with a reliable reference data standard.
