摘要:
A plurality of multicolored transparencies or pictures having different parallactic views of a scene are aligned with each other and illuminated by red, green, and blue coherent beams. The resulting images are focused on a holographic recording medium through an aperture elongated along the direction of the alignment of the pictures. A hologram is recorded by red, green, and blue coherent reference beams directed at the recording medium. The images are reconstructed with a white reconstructing beam or a reconstructing beam composed of quasi-monochromatic colors and observed through an aperture corresponding to the first aperture and arranged in the same position. The hologram has recorded thereon a focused image hologram of the pictures and a Fresnel hologram of the aperture. The reconstructed image may be expanded by a screen which is directive in one direction, i.e. retroreflective horizontally, and dispersive in another direction, i.e. vertically dispersive.
