摘　　要：介绍了光学积分器的光学结构及其工作原理,阐述了利用光学积分器提高太阳模拟器辐照面均匀性的几种方法,并讨论分析了光学积分器像差、光通道数目的选取、边缘补偿、适当扩大积分器口径及投影镜离焦对系统辐照面均匀性的影响。这些将对光学积分器的优化设计具有一定的指导作用。This article described the optical structure and the operating principle of the optical integrator,and expounded several methods to improve the irradiation uniformity of the sun simulator by the optical integrator. Then,it discussed and analyzed the effects of each method on the irradiation uniformity of the sun simulator,including aberration,selection of the number of optical channel,edge compensation,appropriately enlarged the aperture of integrator and defocus for projective lens of the optical integrator. These would have certain guidance functions to optimization design of the optical integrator.
