| 中文摘要: |
| 利用光线追迹与实验的方法,对菲涅耳透镜在平行光照明时的成像特性进行了分析.给出了在各种角度入射情况下的最佳像点位置及像点弥散斑大小,通过对结果进行分析,得出了最佳像面曲线及其特征与参数.并讨论了它们与菲涅耳透镜参数的关系. |
| 英文摘要: |
| ]Imaging characteristic of Fresnel lens for parallel incident rays is analyzed by ray tracing and experiments.The optimal focus position and the size of diffused image for different incident angle are presented.The expression of optimal focus plane is developed and the relationship between focus plane and the Fresnel parameters is also discussed here. |
