Paper Abstract

We map the transverse profile of light beams using photon-number-resolving detectors, and observe compression of beam profiles for higher detected photon-number. This compression is exploited to enable contrast enhancement between two point images separated at the Rayleigh limit. This enhancement exists for all separations up until the classical Sparrow limit.
