摘　　要：为了满足月球模拟器辐射亮度和特定月相模拟的技术要求,针对传统的月球模拟器基于太阳模拟器工作原理只能实现月球辐照度的模拟,提出了一种基于月球真实亮度模拟的月球模拟器光学系统设计方案。结合月球模拟器的技术指标,使用LED拟合光源作为设计核心,根据月球照度、太阳光谱和人眼视觉函数计算出月球真实辐射亮度,设计符合真实亮度要求的月球模拟器光学系统并利用lighttools软件对LED拟合光源进行辐射亮度仿真。根据特定月相模拟以发光面圆心为基准的设计理念,阐述了发光面圆心位置转换的测试方法,并对精度进行分析。试验与仿真结果表明:月球模拟器光学系统可实现真实亮度模拟以及圆心位置精确定位。In order to meet the technical requirements of the radiance and specific phases of the moon for moon simulator,aiming at the fact that traditional moon simulator based on the principle of the solar simulator only can achieve the irradiance simulation of the moon,an optical system design scheme based on the real moon radiance simulation is proposed.Considering the technical specifications of the moon simulator,using LED fitting source as design core,according to the moon irradiance,the solar spectrum and human eye visual function,the true radiation of the moon is calculated,the optical system of the moon simulator complying with the real radiance requirement is designed; and lighttools software is utilized to simulate the radiance of LED fitting source.According to specific moon phases,the design idea of taking the circle center of the radiation surface as the benchmark is simulated,the test method of the circle center position transformation of the radiation surface is explained and the accuracy is analyzed.Experiment and simulation results show that the optical system of the moon simulator can simulate the real radiance and locate circle center position accurately.
