摘　　要：太阳模拟器中最重要的技术指标之一是辐照均匀度,文中论述了太阳模拟器的工作原理,并对太阳模拟器辐照面辐照均匀性进行了深入研究。根据太阳模拟器的工作原理,分析了光学积分器的像差、投影镜离焦量及边缘补偿对太阳模拟器辐照面辐照均匀性的影响,并采用ZEMAX软件仿真分析了准直物镜对辐照面均匀性的影响。结果表明,准直物镜对辐照均匀性影响较小,而影响系统辐照均匀性的主要因素是光学积分器。通过理论分析,计算得出了所设计的太阳模拟器系统辐照不均匀度为2.7%,结果满足设计要求。Irradiance uniformity is one of the significant qualifications of a sun simulator. In this paper, the operating principle of the sun simulator is introduced, and the irradiance uniformity of the sun simulator is studied in detail. Then, based on the operating principle of sun simulator, the effects of the aberration, defocus for projective lens and the edge compensation of the optical integrator on irradiance uniformity of the sun simulator are analyzed, and by ZEMAX software the influence of a collimator lens on the irradiance uniformity is simulatelly analyzed also. Analyzed results show that main effect factor on the irradiance uniformity of sun simulator is optical integrator, and the collimatator lens has a little effect on it only. By theoretical analysis, the irradiance non-uniformity of designed sun simulator is 2.7% , which meet the design requirements.
