Paper Abstract

In this paper, the design theory of a computer-generated quadruple focus holographic lens is described. The holographic lens is required to have the identical diffraction performance for the four focuses. Because the fringe pattern of the hologram can be expressed with mathematical equations, the principle of computer holographic interferogram is adopted. We present an area division method for the design of multi-focus computer- generated holograms. The mathematical model, computing process and an example of design ar given int his paper.
