Abstract
An electronic device may include a camera, a lens, and gratings overlapping the lens. The gratings may diffract a first portion of light incident from a first range of incident angles while transmitting a second portion of the light incident from a second range of incident angles. The lens may direct the second portion of the light to the camera. The gratings may diffract the first portion of the light away from the optics. The gratings may be homogenous or spatially varying. If desired, the gratings may diffract the first portion of the light into a waveguide that propagates the first portion of the light away from the optics. The first range of incident angles and/or the location of the gratings may be selected to remove stray light that would otherwise produce artifacts in the image data. The camera may be replaced with an eye box in augmented reality implementations.
