高光谱紫外辐照度仪CCD电路系统的设计及测试
Design and test of CCD circuit system of hyperspectral UV irradiance monitor
摘要
Abstract
In order to obtain the solar ultraviolet direct spectral irradiance with high signal-to-noise ratio on the ground,an ultraviolet sensitive linear array CCD detector was selected,and a prototype of a hyperspectral ultraviolet irradiance monitor was developed.The CCD circuit system was designed.The working principles and design methods of power supply circuit,driving circuit,analog front-end circuit and timing sequence of CCD driving were discussed.The nonlinearity and signal-to-noise ratio of the CCD circuit system were tested in the laboratory using a standard light source.The results show that in the 340 nm band,when the signal received by the CCD detector reaches about 80%of the saturated signal,the signal-to-noise ratio of the system exceeds 400.Finally,the tested CCD circuit system and the optomechanical module were assembled,and the wavelength calibration of the assembled spectrum module was carried out.It is shown that the hyperspectral UV irradiance monitor covers a spectral range of 280～400 nm,which meets the working requirements of the monitor for UV hyperspectral measurement,and verifies the rationality and feasibility of the CCD circuit system design.关键词
