One main problem of an interferometric measurement is to evaluate the object distance from the interference function. One of the known methods that delivers the object phase is the phase step method. Here we introduce computer-generated holograms to realize parallel phase steps without phase modulation of the reference path.
干涉测量的一个主要问题是根据干涉函数评估物体距离。已知的获取物体相位的方法之一是相位步进法。在此，我们引入计算机生成全息图，以在不调制参考光路相位的情况下实现并行相位步进。
