Linear and nonlinear light localization through scattering media.

Abstract

We extend the principles of time-resolved super-resolution source localization from diffractive microscopy to the imaging of objects through scattering media. We show that isolation and localization of the scattering (versus diffractive) point-spread function can be done by individually illuminating or individually darkening image segments. We experimentally demonstrate reconstruction of both bright and dark sources. Further, we show that self-focusing nonlinearity improves the localization accuracy for bright sources.
