Abstract
A method includes capturing light reflected off one or more objects and splitting the captured light into a plurality of light fields with a plurality of phase curvatures. The method further includes generating, for the one or more objects, a plurality of holograms based on the plurality of light fields and determining, for each of the plurality of holograms, an intensity and a phase-shift of the hologram. The method thus includes generating a depth map comprising depth information for the one or more objects based at least in part on a function determined by the respective phase-shifts of the plurality of holograms.
