Abstract
A double images hiding technology based on optical interference is proposed. The images are hiding into two computer generated phase only masks which are located at the determined positions. Two beams propagate through the masks and interfere at the preset positions. The desired images will appear at the preset positions. The positions coordinates and wavelength can also be used as encoding parameters. Computer simulations show the validity of this new method.
