用角谱法计算菲涅尔衍射图样，计算出后加上GS算法即可得出全息图-Fresnel diffraction pattern is calculated using the angular spectrum method, after adding GS algorithm to calculate the hologram can be derived

The GS method is an iterative algorithm for solving non linear algebraic equations. An initial solution vector is assumed, At every subsequent iteration, the solution is updated till convergence is reached. The GS method applied to po
