采用Ｇｅｒｃｈｂｅｒｇ－Ｓａｘｔｏｎ（Ｇ－Ｓ）的迭代算法，在物域和频域之间进行多次迭代，使频谱的振幅大致为常数，并对频谱的位相进行量化，用二元光学技术制成了８台阶反射式相息图（ｋｉｎｏ－ｆｏｒｍ），再现时获得了清晰的像，衍射效率较高。
Using the iterative algorithm of Gerchberg-Saxton (G-S), iterations between the object and frequency domains are performed to make the amplitude of the spectrum approximately constant and to quantize the phase of the spectrum. Binary optics are used 8-step reflective phase diagram (kino-form), reproduce a clear image, diffraction efficiency higher.
