The viewer wears low-cost eyeglasses which contain a pair of analyzing filters (circular polarizers mounted in reverse). Light that is left-circularly polarized is extinguished by the right-handed analyzer; while right-circularly polarized light is extinguished by the left-handed analyzer. The result is similar to that of steroscopic viewing using linearly polarized glasses; except the viewer can tilt his head and still maintain left/right separation. Many cinema systems today use electronically driven circular polarizers that alternate between left- and right- rotation directions, and does so in sync with the left or right image being displayed by the (digital) movie projector.
