摘　　要：星模拟器是为模拟真实的恒星物理特性而设计的,由于不同恒星的色温和星等不同,为了更真实地模拟恒星,需要星光光源模拟系统能够实现色温和星等大范围高精度可调。该系统由积分球、光源模块、控制模块以及光纤光谱仪构成闭环光源模拟系统。为保证出射光的均匀度,采用了溴钨灯和多种单色LED混光作为光源,用恒流驱动方式控制LED的输出亮度。引入量子行为粒子群算法作为光谱匹配算法,求解LED系数ai。随着迭代次数的增加,适应度函数的值达到最小,则色温和星等的模拟误差变小。经实验验证:实现了色温3 000、4 300、5 500、6 500、7 600、20 000 K的模拟,色温匹配误差优于±10%;模拟星等+2~+8.5 Mi可调,星等匹配误差优于±6%。The star simulator was designed to simulate the physical characteristics of real stars. Due to the different color temperatures and magnitudes of different stars, in order to simulate stars more realistically, a starlight source simulation system was required to achieve large-scale high-precision adjustment of color temperature and magnitude. The system consisted of an integrating sphere, light source module, control module and fiber spectrometer to form a closed-loop light source simulation system. In order to ensure the uniformity of the emitted light, a bromotungsten lamp and a variety of monochromatic LED mixed light were used as the light source, and the output brightness of the LED was controlled by constant current driving. The quantum behavior particle swarm algorithm was introduced as the spectrum matching algorithm to solve the LED coefficient ai. As the number of iterations increases, and the value of the fitness function reached the minimum, the simulation error of color temperature and magnitude became smaller. Experimental verification: The range of color temperature was 3 000, 4 300, 5 500, 6 500, 7 600, 20 000 K, the color temperature matching error was better than ±10%;the range of simulated magnitude was +2-+8.5 Mi, and the magnitude matching error was better than ±6%.
