We worked on a method for extracting three-dimensional information from holographic interference fringe patterns by using an interferometer. So far, we identified the matching method by using the sum of products and the method that used an optical correlation system. In the handling that used the optical correlation system, we made a lot of masks for the depth direction and had to exchage them. In the work described in this paper, we used only one mask as complex amplitude distribution instead of the amplitude distribution, Here we present the method that extracts three-dimensional information by sifting the plane of observation phase information data with the improved optical correlation system.
