Abstract: 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.

Abstract: An autostereoscopic display includes an image forming device and a substrate having alternating strips, where strips having a first optical property are separated by strips having a different optical property. This substrate may be composed of alternating strips of polarization film separated by clear, nonpolarizing strips. Alternately, this substrate may be composed of first alternating strips that retard a component of linearly polarized light by one-half wavelength, separated by second alternating strips that retard a component of linearly polarized light by one wavelength. A removable., separate polarizing substrate may be removably placed in front of the substrate containing the alternating strips. When the removable polarizing substrate is placed in front of the strips in certain orientation, autostereoscopic imaging is viewed by the observer, and when this polarizing substrate is removed, 2D imaging is viewed.

Abstract: The invention relates to an attachment for a light-emitting video projector, the beam of which contains a left and right stereo half-image adjacent to each other, for the 3-D projection of stereo images on a projection surface, upon which the projection planes are essentially maintained for observation with polarised spectacles. The aim of the invention is to develop a generic attachment in order to avoid the disadvantages of the state of the art and with which stereo images are produced on a projection surface, essentially retaining the polarisation planes and which may be observed with simple polarised spectacles. Said aim is achieved, whereby in one embodiment of the attachment, said attachment, comprises two rotatably arranged mirrors (2) and a filter with a retarding film (3), for rotating the direction of polarisation of the light by 90 DEG . The retardation filter (3) and the two mirrors (2) are aligned relative to each other such that only the light beam of one of the both stereo half-images is rotated by the retarding filter (3) in the polarisation direction thereof and both stereo half-images are projected upon each other on the projection surface (5).

Abstract: A system and method for the display of multi-aspect stereo imagery. The system comprises a controller that presents multi-aspects of an object sequentially to an LCD screen. The LCD screen is illuminated and projected onto an image aspect block. The image aspect block further has a polarizing screen that is actuated by the controller when the LCD image is to be projected onto a holographic screen. As the next image aspect is presented to an observer, the observer can see the object in stereo since two aspects are being presented to the observer. When the image formation block polarizing screen is not energized, light from the LCD passes through the image aspect block to the next image aspect block which will then reflect the image onto the holographic screen if the associated polarizing screen is actuated by the controller. In this way two views are presented to the observer for creation of the stereo effect.

Abstract: The present invention relates in general to systems for and methods of three-dimensional viewing of displays and projections. One embodiment two layers (50, 90) are uniform polarizing filters and a birefringent layer with individually switchable elements (60) is sandwiched between them. Together these layers (50, 60, 90) constitute a parallax layer (40). This parallax layer (40) is located at a certain distance from a display (10). This placement, and the existence of opaque areas on the parallax layer (40) which permits to a viewer see a three-dimensional image. The individual elements (601-615) of the birefringent layer (60) are controlled by a control element (80), which is in communication with a head-tracking sensor (85). This allows the individual elements (601-615) of the birefringent layer (60) to be selectively turned on and off according to the position of the viewer's head.

Abstract: A polarizing modulator for use in an electronic stereoscopic display system having a sequentially scanning display includes a plurality of liquid crystal segments arranged contiguously in a direction of the sequential scan. The liquid crystal material used in each segment has its phase shift tuned to eliminate the perception of a visible line between segments. In a preferred embodiment, the phase shift is tuned by applying a bias voltage to the liquid crystal in its low state.
