Abstract

With the exceptional development and popularization of laser holography, the application of the holographic anti- counterfeiting identifiers is enlarging gradually. How to improve the quality of holograms for laser holography industries becomes very important. In recent years computer- generated holograms have been investigated intensively because of their wide application range and their advantages in term of flexibility, accuracy, light weight and cost. A method based on Iterated Function System for digital hologram synthesis is proposed in this paper. The method can generate the view angle combining digital holograms by resolving the affine transforms of IFS into many affine transforms of sub- images. The reconstructed sequence of images with multi- channel can be viewed in different angles and look like a kinetic-object. Thus our method provides a new way to laser holography anti-counterfeiting. The generated fractal kinetic holograms have been used in many security holograms.
