Abstract
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.
