Abstract
Metasurfaces and systems including metasurfaces for imaging and methods of imaging are described. Such metasurfaces may be formed on a substrate from a plurality of posts. The metasurfaces are configured to be optically active over a wavelength range and in certain embodiments are configured to form lenses. In particular, the metasurfaces described herein may be configured to focus light passed through the metasurface in an extended depth of focus. Accordingly, the disclosed metasurfaces are generally suitable for generating color without or with minimal chromatic aberrations, for example, in conjunction with computational reconstruction.
