Abstract
A light transmissive panel comprising a first sheet and a second sheet, wherein each sheet is made up of a non-birefringent substrate and a wire grid polarizer pattern of continuously varying absorption axis orientation formed on the non-birefringent substrate. The wire grid polarizer patterns on each of the first and second sheet are mechanically translatable relative to each other, wherein the mechanical translation controls transmission of light through the light transmissive panel. Light transmissive panels wherein each sheet of the panel is made of a wire grid polarizer that is laminated with a continuous variable thickness wave plate retarder, wherein the continuous variable thickness wave plate retarder rotates input light by an amount determined by the thickness of the wave plate retarder.
