Abstract
Systems and methods of the present disclosure provide a compact camera device that utilizes one or more spatially varying polarizers, such as one or more multi-twist retarders, to provide compact designs with improved performance. The spatially varying polarizers may be used to multiplex light received by a camera, which allows optics to modify (e.g., focus) incident light in a polarization specific manner to provide better resolution, reduced form factor, or other advantages.
