(57) ABSTRACT
A system for producing a white-light interference hologram includes a camera adapted for recording a first and a second bitmap image ol a scene from separate vantage points, and the separation distance ol the vantage points, a computing engine adapted to compute three-dimensional x, y, and z characteristics ol an interference hologram topology for the scene from the bitmap image and separation data, wherein x and y are two dimensional locations olbits in a bitmap ol the topology and z is a depth dimension for each x,y bit, and a printer adapted to print in color the x,y bitmap, and to create the depth dimension z at each x,y bit location, providing thereby a three-dimensional interference hologram topology for the scene. In a prelerred embodiment the depth dimension is created by electrophoresis, using a medium having an electrophoretic gel layer, with the ink applied to the gel in a bit-mapped pattern being ionic in nature, and capable ol being migrated in the gel layer by electrophoresis. In other embodiments the third dimension is provided by using magnetic ink and migrating the bits using controlled magnetic fields.
