| Abstract: | 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. |
