Optimizing the design of an embedded grating polarizer for infrared polarization light field imaging

A silica-based embedded aluminum grating polarizer suitable for a near- and mid-infrared light field camera is investigated to fully utilize the direction information recorded by the detector in the light field camera. A grating with good polarizer performance was obtained by using the finite-differ...
