Abstract

In part I of a previous study [Appl. Opt. 37, 6937 (1998)] we introduced what is believed to be a novel two-dimensional (2-D) fuzzy-logic optical controller. The complexity of such a setup when we deal with an N-dimensional control procedure leads to a more compact version both in planning demands and in space. Viewing the pros and cons of the 2-D setup, we seek a simpler model and find it in a one- dimensional (1-D) multilayer setup. Here we explain the process of finding the optimal 1-D setup and support the concept with true optical results. The new 1-D optical controller is modular and easy to build, and the results that it yields are quite satisfactory.
