Abstract

Optical filters which are capable of performing discrete two-dimensional coordinate transformations for space-variant image processing are described. Several examples of space variant image processing are given, including the application of conformal mapping to a problem in potential flow theory. With simple optical arrangements, both the forward and inverse transformations can be performed with the same filter. Production of these filters by a microcomputer controlled scanning Interferometric Pattern System is detailed.
