Abstract

This invention relates to a three-dimensional image display device comprising two or more parallel elements, each element being formed from a transparent material, each element having a coating formed thereon, the coating including means for reflecting a portion of a beam of light having a selected predetermined orientation of a chosen component of electric field vectors and means for passing the remaining portion of the beam of light. The coating may also include an absorbing means including a dielectric absorbing means for a photo responsive means including a dielectric sensitive means.

Claims

1. A three-dimensional image display device comprising three parallel elements each element forming an image plane for a projected beam of light having components of electric field vectors each element being formed from a transparent material, each element having a coating formed thereon, the coating adapted to reflect a selected portion of the projected beam of light having a predetermined orientation of a chosen component of the electric field vectors and to pass the remaining portion of the projected beam of light.

2. A three-dimensional image display device as described in claim 1 and wherein the coating for each element is formed of a dielectric material.

3. A three-dimensional image display device comprising two or more parallel elements each element forming an image plane for a projected beam of light having components at a predetermined orientation, each element being formed from a transparent material, each element having a coating formed thereon, the coating for each element including an absorbing means for absorbing a portion of the projected beam of light having a selected predetermined orientation of a chosen component of electric field vectors and means for passing the remaining portion of the projected beam of light.

4. A three-dimensional image display device as described in claim 3 in which the absorbing means includes a dielectric absorbing means.

5. A three-dimensional image display device for displaying an image from a 3-D projector which is adapted to form a projected beam of light having components at a predetermined orientation, said image display device comprising three or more parallel elements, each element forming an image plane for the projected beam, each element being formed from a transparent material, each element having a coating formed thereon, the coating for each element including a reflecting means for reflecting a portion of the projected beam of light having a selected predetermined orientation of a chosen component of electric field vectors and means for passing the remaining portion of the projected beam of light.

6. A three-dimensional image display device as described in claim 5 in which the reflecting means includes a dielectric reflecting means.
