Abstract: A METHOD FOR PREPARING A PLURALITY OF SUBSTANTIALLY IDENTICAL REPLICAS OF SURFACE DEFORMATION IMAGES, E.G., PHASE HOLOGRAMS IS DISCLOSED. BASICALLY, THIS PROCESS INCLUDES THE STEPS OF FORMING A FIRST GENERATION REPLICA BY CASTING AGAINST THE ORIGINAL SURFACE DEFORMATION IMAGE, FORMING A SECOND GENERATION REPLICA BY CASTING AGAINST THE FIRST GENERATION REPLICA, TRANSFERRING THE CAST SECOND GENERATION REPLICA TO A SUPPORT SURFACE, AND REPEATING THE SECOND GENERATION CASTING AND TRANSFER STEPS. THE METHOD MAY INCLUDE THE STEPS OF FORMING A METAL MASTER FROM THE SECOND OR THIRD GENERATION REPLICA AND STAMPING A PLURALITY OF SIMILAR REPLICAS USING THE METAL MASTER.
