Paper Abstract

An optical correlator combining most of the features required by a practical automatic control system has been built and used to control small series of work pieces. With the holographic matched filtering technique the optimization of the spatial filter leads to a well-defined response curve which is used to calibrate the output of the optical correlator in terms of shape error. It is shown, that the techniques of computer holograms offer the widest possibilities to perform this optimization. Simple examples show the capability of detecting shape errors of a few microns.
