Abstract
Various aspects of the present disclosure are directed toward methods, systems, and apparatus that include an optical detection node to pass light through the optical pathway to the optical detection node where the light is detectable. At least one focusing element is provided to pass the light along the optical pathway, and at least one optical mask is used to provide spatially-varying modulation on the light passing along the optical pathway. The light passing along the optical pathway is redirected and modified to create a spiral point spread function at the optical detection node for estimating a distance to an object that is characterized at least in part by the light passing along the optical pathway.
