Extraction of Zernike Coefficients Modes using Holographic Wavefront Sensing: Modeling and Simulation
Keywords:
Zernike aberration modes, wavefront sensing, Fourier transform, computer-generated hologramAbstract
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
