Efficient superoscillation measurement for incoherent optical imaging

I propose a superoscillation measurement method for subdiffraction incoherent optical sources, with potential applications in astronomy, remote sensing, fluorescence microscopy, and spectroscopy. The proposal, based on coherent optical processing, can capture all the light on the aperture in principle, perform better than direct imaging on statistical terms, and approach the fundamental quantum limit.Comment: 13 pages, 5 figures. v4: accepted by IEEE Journal of Selected Topics in Signal Processin
