Abstract
One main problem of an interferometric measurement is to evaluate the object-distance from the interference function. One of the known metho ds that delivers the object phase is the phase step method. Here we in troduce computer-generated holograms to realize parallel phase steps w ithout phase modulation of the reference path.
