Abstract

Traditionally, the resolving power of passive optical imaging systems was understood to be determined by the Rayleigh resolution limit. However, a rigorous analysis of the two-point resolution problem using Quantum information theory has demonstrated that the Rayleigh limit is not fundamental. In fact, we now know that the fundamental quantum optical resolution limit can be achieved by spatial mode de-multiplexing (SPADE) or mode sorting measurements. In this talk, I will discuss our work on pursuing a broader understanding and analysis of the quantum limits of passive optical imaging in the sub-Rayleigh domain (i.e., optical super-resolution) for more complex scenes (such as point source constellations, continuous line sources etc.), including use of adaptive imaging and applications to coronagraphs and multiple-aperture imaging systems.
