An alternative holographic wavefront analiser scheme based on the light guide plate with computer-generated holograms and diffractive optical element is proposed. Advantages of the scheme are the absence of a maximum of zero order of diffraction in the photodetector plane and potentially better recognition of aberrations.
A holographic wavefront sensor scheme using a phase-only spatial light modulator (SLM) with reduced cross-talk noise influence is proposed. A novel method for plane wave aberration measuring using a phase-only computer-generated hologram is devised. The proposed scheme and algorithm are validated with numerical simulations and experiments.
