Abstract:
A device for converting image data into a holographic pattern formed from a plurality of discrete holograms each constituting a holographic pixel and having diffraction gratings, said device comprising:(a) means for converting said image data into digital form having a plurality of digital data characteristics; (b) an optical system arranged for manipulating a laser beam according to said digital data characteristics by splitting said laser beam into a reference beam and at least one object beam; (c) means for irradiating a profileable surface with said reference beam and at least one object beam to sequentially form each of said holograms as a holographic pixel, each of said holographic pixels having a distinct interference pattern, said interference pattern of each said holographic pixel having characteristics of a corresponding discrete portion of said image data.
