在近代激光测试技术中多面体旋转反射扫描测试系统存在入瞳漂移的问题,带来测试误差,然而经典资料中均未作讨论.本文在理论上推导了激光扫描测试系统中的入瞳漂移,详尽讨论了八面体旋转反射扫描测试系统的入瞳漂移问题,并且分析了旋转半径及入射角与入瞳漂移的关系,得出精确的结论.实际应用中如何根据精度要求设计旋转反射镜、如何选择入射角、f-θ物镜设计中如何考虑入瞳漂移的影响均可利用这一结论. 相似文献

The method of multifactorial orthogonal decision on diffraction efficiency (DE) of Fresnel hologram is proposed in this paper. The orthogonal table is designed for such major manufacturing parameters as beam ratio, expo sure, development time and developer density. With variance analysis, the conspicuous factors on DE are obtained, and the optimal technological conditions are established. In addition, by regression analysis to the conclusion, we obtain a fit rate of about 88% to the calculated and experimental results. 相似文献
