Abstract:

By exploiting the notion of orbital angular momentum of light beams, we have recently demonstrated a novel pupil-phase-engineered point-spread function (PSF) design in which as a function of defocus the PSF merely rotates without changing its shape materially over a considerable range of defocus values. Here we explore general properties of the rotating PSF design with respect to 3D imaging, including trade-offs between transverse and longitudinal resolutions. We also present the results of simulation of reconstruction of 3D scenes consisting of point sources from noisy image data based on this design.
