介绍了太阳模拟器的组成及工作原理。在非成像光学的光学扩展量基础上，对照明系统和投影成像系统进行了光学匹配，并从拉赫不变量的角度分析了能量在整个系统中的传递情况，得出椭球聚光镜、光学积分器和准直物镜这三者的相对孔径相互之间的最佳匹配关系，即三者的相互之间的相对孔径值均为1／4时，满足光瞳衔接原理。计算得到了从物面到像面的拉赫不变量为0．45，验证了整个光学系统从物面到像面的拉赫不变量守恒，有效地利用了光学系统的光能。

This paper introduces the composition and operational principle of solar simulators. Based on the extence concept of non-imaging optics, the whole system including an illumination system and a projection im- aging system are matched, and the energy transfer in the whole system is analysed on the basis of Lagrange in- varian. The best matching relationship of relative aperture 1/4 among the ellipsoid condenser, optical integra- tor and the collimated object lens are obtained and satisfies the pupil connected principle. This calculated val- ue of Lagrange invariant is 0.45, which verifies that the Lagrange invariant is conserved from an object surface to an image surface. So the optical energy of the optical system is used effectively.
