    Approaching Quantum-Optimal Imaging without Prior Knowledge of the Object Location (CTh4C.7)
    Presenter: Michael Grace, University of Arizona

    Spatial-mode-sorting (SPADE) receivers surpass Rayleigh’s criterion for incoherent imaging but are sensitive to nuisance parameters (e.g., misalignment). Our multistage detection strategy uses preliminary physical measurement(s) to build up required prior information for near-quantum-optimal, sub-diffraction imaging.

    By allowing phase in the image plane to be a free parameter, we experimentally demonstrate multilevel diffractive lenses via inverse design in almost the entire electromagnetic spectrum for applications like achromaticity, depth-of-focus, wide-angle imaging, etc.

    Study on Multicolor Three Dimensional Display based on Organic Up-conversion Materials (ITh5E.4)
    Presenter: Hongyue Gao, Shanghai University

    A three dimensional (3D) display method is investigated with liquid organic up-conversion materials as spatial screen. Under the excitation of laser, two color fluorescence can be achieved in the spatial screen. We present blue color and red color excited 3D images in the up-conversion liquid, which has potential application in 3D projection.
