Abstract
A system including a first micro-retarder array, wherein the first micro-retarder array is configured to convert a purely polarized light of an incident light into two components. The system additionally includes an optical device, wherein the optical device is configured to collimate the two components to two foci planes. Moreover, the system includes a second micro-retarder array, wherein the second micro-retarder array is configured to combine a set of two components of the incident light, thereby producing a second purely polarized light. Further the system includes a detector, wherein the detector is configured to receive the second purely polarized light.
