摘要：

A light source of multi-star simulator capable of background adjustment and magnitude control has been designed.Two integrating spheres are employed as the star-point light source and the background light source respectively.A beam splitter prism has been designed to serve as the beam combiner for the star-point and the background light sources,and a mathematical model has been constructed respectively to compute the light flux of the two integrating spheres.A magnitude testing system and a background testing system have been created using low-light illuminometer,luminance meter,and testing instruments to measure the star-point magnitude and the background luminance of the multi-star simulator.The test results suggest that the star-point magnitude is adjustable from0 to+5 mv,with a simulation precision superior to ±0.026 mv.The maximum background luminance is 3.8×10～5 cd·m-2,and the minimum background luminance is6.4×10-2cd·m-2.The designed light source system can meet the requirements for simulating the stellar map with a sky background.
