Abstract

We use speckle intensity correlations to image incoherent illuminators inside scattering samples. Our approach uses correlation properties specific t o s peckle patterns created by near-field illuminators. Compared to previous far-field approaches, our approach achieves order-of-magnitude expansion in both the range and density of illuminators it can recover.
