Abstract

A holographic wavefront sensor based on a spatial light modulator (SLM) for displaying computer-generated holograms (CGH) is a flexible and simple method for analyzing the wavefront. This article discusses an algorithm for the synthesis of holographic structures based on a blazed diffraction grating (Echelette grating). As a result of the reconstruction of such CGHs the light diffracts predominantly into one diffraction maximum. The experiments carried out confirm the effectiveness of the proposed algorithm when measuring the wavefront described by one or several Zernike polynomials simultaneously.
