HOLOGRAPHIC STEREOGRAM AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To make bondaries of element holograms hardly visible in a one-step Lippmann holographic stereogram or a multidot system holographic stereogram. SOLUTION: A holographic stereogram H is produced by one-dimensionally or two-dimensionally arranging element holograms a1 to an to aN in which the sampling information of the surface information in different observation directions of a three-dimensional object is recorded in volume holograms. The diffracted light B' from the aforementioned stereogram H and referential light are made to interfere with each other and recorded in another volume hologram photosensitive material 10. In the obtained stereogram, the discontinuous part between element holograms is recorded as separated from the hologram plane.
