This talk describes our recently-developed guidestar-free approach to imaging through scattering and other optical aberrations; neural wavefront shaping (NeuWS). NeuWS integrates maximum likelihood estimation, measurement modulation, and neural signal representations to reconstruct diffraction-limited images through strong static and dynamic scattering media without guidestars, sparse targets, controlled illumination, nor specialized image sensors. We experimentally demonstrate guidestar-free, wide field-of-view, high-resolution, diffraction-limited imaging of extended, nonsparse, and static/dynamic scenes captured through static/dynamic aberrations.
Adversarial sensing is a self-supervised, learning-based approach for solving inverse problems with stochastic forward models. The basic idea behind adversarial sensing is that one can use a discriminator to compare the distributions of predicted and observed measurements. The feedback from the discriminator thus allows one to reconstruct a signal from observations from stochastic forward models without solving for any the forward model’s unknown latent variables. While adversarial sensing requires no training data, it can be modified to incorporate pretrained deep generative models for use as priors. This paper highlights some of our recent work on applying adversarial sensing to imaging through turbulence and to long-range sub-diffraction limited imaging with Fourier ptychography.
