ABSTRACT:
Described are stereoscopic eyewear, methods and systems for manufacturing the same. The stereoscopic eyewear includes right- and left-eye filters for analyzing stereoscopically-encoded polarized light. The filters are made using a roll-type polarizer having an absorption axis. A polymer alignment layer is deposited on a portion of the roll-type polarizer. A liquid crystal polymer (LCP) layer is deposited on the polymer alignment layer. The polymer alignment layer and LCP layer provides at least one retarder having an optic axis at a predetermined angle to the absorption axis of the roll-type polarizer. Described embodiments include a polymer alignment layer that may include at least one of a linearly photopolymizerable polymer (LPP), a brushed or rolled polyimide.
