Paper Abstract

Based on three-fiber optic Moiré interferometric technique, a novel profilometry has been proposed and demonstrated in this paper. The square and hexagon grid interferometric fringe pattern formed by fiber optic interferometric grid generator have been designed and performed. The designing and realizing methods of the fiber optic interferometric grid pattern by using three PM fibers are discussed. Theoretically, the three-fiber coherence optical field intensity distribution has been deduced and the simulation results are also presented. The configuration of the fiber optic Moiré three-dimensional shape measuring system is introduced. For example, a small half-sphere has been used to demonstrate how to reconstruct the three-dimensional shape by fiber optic Moiré interferometric technique.
