Abstract
This disclosure provides systems, methods and apparatus for an imaging system that includes a light guide having light-turning features that are configured to receive ambient light incident on the light guide, including light scattered from a scene to be imaged, and to direct the received ambient light towards an image sensor. The light-turning features may have angle-discriminating properties so that some light-turning features capture light incident upon the light guide at certain angles of incidence, but not others. Light scattered from multiple parts of a scene to be imaged may then be directed to correlated locations on an image sensor, which provides electronic data representing an image.
