RESEARCH OF INTEGRATING SPHERE SOLAR SIMULATING SOURCE

The research of integrating sphere solar simulating source is introduced,in terms of integrating sphere, collecting system,linear dimming system and spectral measurement.The integrating sphere solar simulating source is composed of tow lamps,Xenon lamp and Bromine-tungsten lamp.Tow cut-off filters are used to calibrate and make up the solar radiation spectrum.The power of the tow lamps is given by calculation.The linear dimming system makes the radiance of the sphere exit portal decrease pro rata 10% from the maximum radiance.The integrating sphere solar simulating source is used for radiation calibration of satellite remote sensor.
