Abstract
In the present paper we describe the holographic interferometric beating to produce dynamic photorefractive moiré-like patterns with two or more variation directions. It has been experimentally obtained by the superposition of two sinusoidal gratings with slightly different pitches for each direction of fringe variation obtained. These dynamic moiré-like patterns are induced in the volume of the Bi12TiO20 (BTO) crystal sample used as dynamic holographic medium. The Fourier transform profilometry method is applied using two or more moiré fringe patterns with different direction of variations, simultaneously or not, projected onto an object surface.
