Extraction of Zernike Coefficients Modes using Holographic Wavefront Sensing: Modeling and Simulation

Abstract

Abstract-We propose a holographic wavefront sensor that uses a binary computer-generated hologram (BCGH). This CGH is coded with a single particular Zernike aberration mode with different coeffecients and then all the holograms are multiplexed and binarized to get the final hologram. This multiplexed hologram is used to produce a spots (white pixel on the detector) according to the presence of particular aberration. The Numerical results by Matlab program corresponding to the CGHs are presented.
