ABSTRACT:
A screen construction enables three dimensional perception of projected stereo images without necessarily requiring that the viewer wear analyzing eyeglasses. Three dimensional shadow image data is generated by projecting light towards the screen, through the region of the object or objects to be imaged, from spaced apart light sources each of which produces light coded in a different manner. The screen construction has an array of linear, parallel bands of light analyzing material. A first group of the bands transmit light from only one of the sources and are alternated with ones of a second group of the bands which transmit only light from the other of the sources. A lenticular screen between the array of bands and the viewer restricts visibility of one group of bands to one eye of the viewer and restricts visibility of the other group of bands to the other eye of the viewer.
