Abstract:
A system for fabricating a micropolarization panel for use in stereoscopic viewing a 3-D object recorded in a spatially multiplexed image of said 3-D object, said system comprising:film providing apparatus for providing a supply of film material characterized by an ability to either phase shift or polarize light passing therethrough; film coating apparatus for coating said film material with a protective mask having a predetermined pattern that exposes preselected parts of said film material; and film treating apparatus for treating said film material with said protective mask so as to permanently form first and second optically transparent patterns therein, wherein said first optically transparent pattern imparts a first polarization state, P1, to light emanating from pixels through said first optically transparent pattern, and said second optically transparent pattern imparts a second polarization state, P2, to light emanating from pixels through said second optically transparent pattern, and wherein said first optically transparent pattern is a logical inverse of said second optically transparent pattern; and film cutting apparatus for cutting said treated film material so as to form a micropolarization panel for use in stereoscopic viewing of a 3-D object recorded in a spatially-multiplexed image of said 3-D object.
