To make holograms from computer graphic (CG) in a short time, a new holographic three dimensional (3D) printer is proposed here. This printer consists of galvanometer scanners, a micro computer and a laser, and uses a holographic contact duplicating method. Experiments have shown that a hologram of 39 ×41 mm can be obtained in 4 min.

Key words : hologram, three dimension, galvanometer scanner, printer
