Paper Abstract

A non-scanning method to describe the 3D profile of a metal surface is proposed. A fringe pattern is posited in front of the metal surface. A virtual image of the fringe pattern is formed behind the metal surface. Fringes on the virtual image are deformed by topography of the metal object. Thus, phase of the deformed fringes is desirable to retrieve the profile of the metal surface.
