Abstract
Based on Huygens-Fresnel integral caculation and Lommal function, the paper centeres on how to caculate the approximate value of the common difference between focuses, through analysing the distribution of three-dimensional light near focus. It plays a guiding role, to a certain degree,in the study on the assembly of receiving surface in the system of image formation.
