Query: Inverse Designed Extended Depth of Focus Meta-Optics for Broadband
  Imaging in the Visible   We report an inverse-designed, high numerical aperture (~0.44), extended
depth of focus (EDOF) meta-optic, which exhibit a lens-like point spread
function (PSF). The EDOF meta-optic maintains a focusing efficiency comparable
to that of a hyperboloid metalens throughout its depth of focus. Exploiting the
extended depth of focus and computational post-processing, we demonstrate
broadband imaging across the full visible spectrum using a 1 mm, f/1
meta-optic. Unlike other canonical EDOF meta-optics, characterized by phase
masks such as a log-asphere or cubic function, our design exhibits a highly
invariant PSF across ~290nm optical bandwidth, which leads to significantly
improved image quality, as quantified by structural similarity metrics.
