Abstract:
1. A method of writing a composite 1-step hologram, comprising: generating a laser beam; acquiring digital data from an object, said digital data being described by a luminous intensity tensor performing a single mathematical transformation to convert said luminous intensity tensor writing corrected data to a spatial light modulator, wherein said corrected data is described by said tensor directing said laser beam on to said spatial light modulator so that at least a portion of said laser beam is spatially modulated by said spatial light modulator to form a spatially modulated laser beam; passing said spatially modulated laser beam through an optical objective having a finite distortion, said optical objective focusing said spatially modulated laser beam on to a photosensitive substrate; directing a reference recording beam on to said photosensitive substrate; and forming a double-parallax composite hologram on said photosensitive substrate.
