Computer Generated Hologram Optimization for Lens Aberration.

We propose a lens aberration correction method for holographic displays via a light wave propagation simulation and optimization algorithm. Aberration correction is an important technology to obtain noise-less hologram images in holographic displays. We optimized phase holograms with an automatic differentiation technique and Adam optimizer, and aberration corrected images were achieved. Given an aberrated lens with a focal length of 20mm, the optimized holographic image has a PSNR value of 32.
