Abstract

We propose a projection scheme using a diffraction element for finding the absolute shape of an object with large depth discontinuities. Its application built into an endoscope to retrieve an object inside a body cavity is presented as well. Among all existing fringe projection schemes, this proposed method is notable for its compact design. Only one phase measurement is required. To inspect a dynamic object is desirable.
