Abstract
A scheme of star simulator spectrum simulation based on mixed light source of xenon lamp and halogen tungsten lamp for foundation was proposed.The wide spectrum light source array was composed of xenon lamp and halogen lamp.After color temperature simulation and module controlling,the light entered into the integrating sphere to provide ideal light source for star simulator,and spectral curves were stimulated at specific color temperatures of nearly 3 900K,4 800K,6 500K.Through the simulation of the blackbody spectrum curve of standard,the optimal transmission rate was calculated for each band filter,and the transmission rate of interval in tiny brand was combined for getting the transmission rate which satisfied the design index.The simulation results showed that,by using the proposed scheme,the small band matching simulation error would be less than 10%,with the relative area method verification matching error is within 4%,and this scheme provides an effective method for the star simulator to simulate spectral curves of the specific color temperatures.
