Abstract
Simpler and easier sampling method which is one of the most important parameter required for making holographic stereograms is presented to reconstruct the images from transfer hologram. Instead of fringe-by-fringe sampling method which is difficult to apply in recording holographic stereograms, a new geometrical method is proposed for easier calculation of the sampling numbers. When the slit size is fixed under human pupil size, one can see the full 2D image through a slit. Dividing the distance between the two pupils by slit size, it determines the sampling numbers which are needed for recording. The angle difference of the real object becomes a binocular parallax. And the series of these 2D images are recorded on the master hologram. After processing, it transfers to transfer hologram. As a result, two images which exactly correspond to the places of viewer's eyes can be seen simultaneously. Because the object is taken at different angle and these two images are observed simultaneously, it makes us feel as a real object.
