Abstract
Autostereoscopic images are produced by projecting a stereo pair of images onto a modified cube-corner retroreflective material. The cube-corner differs from that commonly available in that it has been altered to return the light to viewers eyes rather than directly back to the source of the projection.
Claims14
An autostereoscopic image projection system comprising:
- a support structure;
- a left projector mounted on said support structure at a first location for projecting a left multicolor image;
- a right projector mounted on said support structure at a second location for projecting a right multicolor image;
- and
- a modified retroreflective screen for reflecting at least a portion of said left image directly from said left projector to a left eye of an observer and for reflecting at least a portion of said right image to a right eye of said observer so that the reflective image forms an elongated image area for being viewed by the eye of the observer, said left and right projectors being positioned a distance from said left and right eyes.
2 more elements
A method of projecting a stereoscopic image for viewing by an observer, comprising the steps of:
- positioning a left and a right projector a distance from a left and a right eye respectively of said observer, said projectors projecting a left and a right multicolor image respectively on a modified retroreflective screen;
- and
- returning by said retroreflective screen at least a portion of light from said left and right multicolor images directly to said left and right eyes respectively of said observer so that said observer sees a stereoscopic image, a lead portion of light as reflective to said eye of said observer being in the form of an elongated image area.
