Phase diversity, wavefront sensing, neural network

Generalization of learned Fourier-based phase-diversity wavefront sensing

We propose a generalized Fourier-based PDWS method by combining an object-independent network with a system-independent image processing procedure.

Phase-diversity wavefront sensing enhanced by a Fourier-based neural network

We propose an effective neural network based on low-frequency coefficients in the Fourier domain to determine a better estimate of the unknown aberrations.
