ABSTRACT:
A hologram forming system for forming holograms on multiple exposures is provided. In this system, a holographic recording medium is exposed to light beams at least twice at incident angles different between exposures. The incident angle during each exposure process is determined in a given relation to the thickness of the holographic recording medium which tends to vary as the exposure process is repeated so that the reconstruction wavelengths match with target values without shifting between image colors during reconstruction of the hologram.
