Abstract

In principle, PMD needs the two components of the local surface gradient. Therefore a sequence of two orthogonal sinusoidal fringe patterns have to be displayed and captured separately. It is easy and convenient by using a digital display, but it will be much difficult to build a PMD system with mechanic gratings. In this paper, we present a novel phase-shift technique by using the cross fringe pattern, in which a one-dimensional N-phase shift allows for the acquisition of the two orthogonal phases, with only N exposures instead of 2N exposures. Therefore, it make PMD possible be implemented by a one-dimensional translation of the fringe pattern, instead of the common two-dimensional translation, which will be quite useful for certain applications.
