PHASE RETARDANCE AUTOSTEREOSCOPIC DISPLAY

摘要

An apparatus for viewing an image that includes an eye tracker which tracks positions of the eyes of a viewer image. The apparatus includes a display mechanism in communication with the eye tracker which produces a display such that there is a first point and a second point in space whereby the sum of phase is zero for the first point and 0 + 180 degrees for the second point. The apparatus includes a screen on which an image of a superimposed projection for left and right eye views of a viewer is displayed, and projection are also included. The apparatus includes rear and front retarders and means for applying an increasing ramp of phase retardance across an image in the rear retarder, and applying a decreasing ramp of phase retardance across the image in the front retarder so a constant phase retardance is created across an entire surface of the screen disposed behind the rear retarder and the front retarder when seen by a viewer in front of the front retarder.
