摘　　要：为了实现多色温、多星等并且色温和星等都在系统中实时可调节的功能,提出设计一款新型的星等及光谱可调节的单星模拟器系统。系统采用氙灯及卤钨灯作为光源,将光源分为多束窄带光谱,并且对每一束窄带光谱的光强和光谱进行调节实现对黑体光谱范围及色温的模拟。当具有不同光谱特性和色温的光源进入星等调节器时,采用与波段光强控制器不相互干扰的调节方式,只对光源的光度即整个光源的能量进行衰减控制达到星等调节。在实验室实现了整个系统的组装,搭建了控制和测试平台,并给出标准星等光度与各个色温情况下实测星等光度对照结果。In order to achieve multicolor temperature and multimagnitude output, as well as realtime adjusting of magnitude and color temperature, we designed a new type of calibration single star simulator with adjustable magnitude and optical spectrum output. We used xenon lamp and halogen tungsten lamp as the light source~ with different multibeam narrow band spectra with light of varying intensity, we realized the control of spectral band and temperature of star. When the light source with different spectral characteristics and color temperatures went into the magnitude regulator, we only controlled and adjusted the light luminosity of the light energy attenuation. The entire system was assembled in laboratory, and the controlling and testing platform was set up. Besides, the experiments were carried out and the comparison results between the standard magnitude and measured magnitude under different color temper atures were given.
