摘要
分析了光栅的泰伯(Talbot)像和透镜焦面的关系,提出了Talbot像对谱面的对称性原理.并将其用于透镜焦距的测量,方法简单,精度高.
n this paper the relation of Talbot image of a srating and the focal plane of a lens isdiscussed,. The theory of Talbot images symmetry about Fourier spectrum plane is described. The focal length of lens was measuried with this theory, this method is simple and the accuracy. is high.
