Analysis of interferometer with adaptive reference wave

Abstract

Adaptive interferometer based on wave mixing in a photorefractive crystal under alternating electric field Abstract. Our work performs both theoretical and experimental analysis of an interferometric system, which adapts a shape of a reference wavefront to a shape of a measured optical surface using an adaptive optical element. The interferometric system uses a deformable mirror for a wavefront compensation corresponding to the test surface. The accuracy and range of compensation is given by a type of the deformable mirror. It is analyzed a possibility of the application for testing optical surfaces.
