Paper Abstract

The graded-response Hopfield neural network model has been used to solve the traveling salesman optimization problem. However, the mapping of an optical design optimization problem onto a neural net is more difficult. This paper describes how it can be done for the case of minimizing the chromatic aberration in a complicated twenty-element zoom-lens system by the selection of glass types. The problem is combinatorial in nature. It is suited to neural networks, and its solution is non-trivial by other means. Thus the use of neural networks to solve optical optimization problems is demonstrated.
