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.
Index Terms— Zernike aberration modes, wavefront sensing, Fourier transform, computer-generated hologram.
