摘要
光学积分器是太阳模拟器实现均匀辐照的关键光学器件,介绍了光学积分器的组成及其工作原理,阐述了方位偏移误差和倾斜偏移误差对辐照均匀性的影响。根据光学积分器的工作原理,利用软件Lighttools将两种光轴一致性误差对辐照均匀性造成的影响进行了仿真分析。结合实验结果表明,倾斜偏移误差相对方位偏移误差对系统辐照均匀性的影响更为严重。分析光轴一致性误差,可为光学积分器微调机构的设计和实际装调太阳模拟器提供理论依据。
Abstract
Optical integrator is a key optical device of the solar simulator for uniform illumination. The composition and working principle of the optical integrator are introduced, and effect of the azimuth offset error and the tilt offset error of on the irradiation uniformity are elaborated. According to the working principle of the optical integrator, effect of two axis-consistency errors on the irradiation uniformity are analysed by using the LightTools. Combining with experimental results, effect of tilt offset error relative azimuth error on the irradiation uniformity of system is more serious. Analysis of axis consistency error can provide the necessary reference for tuning mechanism of the optical integrator and the practical alignment.
