Holographic setereograms using spatial light modulator

Holographic stereograms were made using a geometrical method easily. Becausethe conventioal sampling metod which is used in cylinder type stereograms, divide the anales of the object so it can't offer a binocular parallax effect very well, and it is also difficult to afficult to apply to the plane type stereograms. In this paper, holographic stereograms were made by use of a new method for the calculation of the sampling number(here, sampliing angles), and the TFT LCD. In order to calculate the sampling angles, geometrical method was used and 2-D images were projected onto diffuser screen through TFT LCD. Result stereorgrams which aremade by a sampling method proposed in this ppaer give a accurate binocular parallax and have a sufficient viewing zone and show that it is possible to make 3-D movies.
