Abstract
An apparatus for viewing an image includes a screen on which an image of a superimposed projection for left and right eye views of a viewer is displayed image. The apparatus includes a mechanism for projecting the projections onto the screen image. The apparatus includes a rear retarder disposed in front of the screen image. The apparatus includes a front retarder disposed in front of the rear retarder image. The apparatus includes a mechanism 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. An apparatus for viewing an image includes a display mechanism 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.
