A theory for making a disk-type multiplex hologram is derived. This theory relates the final image point, as seen by the observer, to a point on the original three-dimensional object through a set of equations. From these equations the distortion of the image and the wavelength as seen by each individual eye can be evaluated. Computer simulation shows the characteristics of this hologram. Some experimental results also confirm these characteristics. By reversing the process and specifying a desired image, we generated a set of distorted two-dimensional originals. The hologram fabricated with these distorted images can generate nearly distortion-free images.

In this paper, a small‐footprint, athermal, hitless, reconfiguration‐optical add‐drop module with an inherently integrated optical power controller is presented. This unique multiplexer cannot only add‐drop any wavelength among designed wavelength channels without interrupting through traffic, but can also dynamically control the output power of an add‐drop channel. © 2003 Wiley Periodicals, Inc.
