The synthetic holography is combined with the digital processing technology of the computer; full-parallax intensity information of a three-dimensional object has been obtained and encoded accurately and effectively by the computer. The encoded information from different visible units of the object is recorded with single-wavelength laser successively on the different dot area of one holographic film. When the obtained film is illuminated by a common lamp, the different intensity information of two view-angles is displayed in each eye, so the stereoscopic image can be obtained. When the line of sight change horizontally or vertically in observation area, the full-parallax reconstructed image will be observed.
