摘　　要：针对以往大型太阳模拟器结构复杂、能量利用率低、均匀性较差等的不足,提出了高能量利用率太阳辐射模拟光学系统设计方法。基于真实氙灯光源的发光特性设计椭球聚光镜,通过添加球面反光镜,利用组合聚光系统提高能量利用率,依据光瞳匹配原则设计光学积分器,利用边缘消杂光法提高辐照均匀性。仿真分析可知:组合聚光系统比单个椭球聚光镜能量利用率提高21.2%,利用边缘消杂光法比边缘补偿法辐照均匀性提高4%。实验结果表明:工作距离20 m,辐照面直径Φ2 m时,最大辐照度为1363.1 W·m^(−2),辐照不均匀度为±4.5%,实现大面积、高能量利用率的太阳光辐射模拟,为航天领域太阳敏感器地面半物理仿真与测试提供有效手段。Aiming at the disadvantages of large-scale solar simulators in the past,such as complex structure,low energy utilization rate and poor uniformity,a design method of solar radiation simulation optical system with high energy utilization rate was proposed.The ellipsoid condenser was designed based on the luminous characteristics of the real xenon lamp.By adding a spherical reflector,the combined condenser system was used to improve the energy utilization rate.The optical integrator was designed according to the principle of pupil matching.The irradiation uniformity was improved by the edge elimination method.The simulation results suggest that the energy utilization rate of the combined condenser system is 21.2%higher than that of the single ellipsoid condenser.The irradiation uniformity of the edge elimination method is 4%higher than that of the edge compensation method.The experimental results suggest that the working distance is 20 m,irradiation surface diameter isΦ2 m,maximum irradiance is 1363.1 W·m^(−2),non-uniformity is±4.5%.It has realized large-area,high-energy utilization rate solar radiation simulation,which provided an advanced means for semi-physical simulation and testing of solar sensors in space field.
