Abstract

The positions and width of the fringes in a binary synthetic hologram are determined by the points at (x,y) that satisfy -q/2 </= x/T + Phi (x,y)/2pi + n </= q/2, where Phi(x,y) is the phase variation of the wavefront, T is the grating period, n is an integer, and q is a constant determining the fringe width. A method for finding an exact solution to this inequality is presented. The feasibility of the procedure has been tested by making binary synthetic holograms. Experimental results are presented, and extensions of the method are discussed.

摘要

二元合成全息图中条纹的位置和宽度由满足-q/2 ≤ x/T + Φ(x,y)/2π + n ≤ q/2 的(x,y)点决定，其中Φ(x,y)是波前的相位变化，T是光栅周期，n是整数，q是决定条纹宽度的常数。本文提出了一种求解该不等式精确解的方法。通过制作二元合成全息图对该方法的可行性进行了测试。给出了实验结果，并讨论了该方法的扩展。
