The Joint Transform Correlator was built using a combination of optical components, analog electronics, and digital electronics. The optical system breadboard can be used to evaluate the correlation process and determine tolerance limits of the optical process. Correlation is achieved using a reference matched filter adjacent to the input image. (Author).

A widely-studied optical correlation architecture, the joint-transform correlator (JTC), can be implemented using either hybrid opto-electronic or real-time holographic approaches. The difference in these approaches is that the former employs digital electronics in the Fourier plane, while the latter uses real-time holographic media.

This report contains a survey of the operation and properties of various types of joint transform correlators, as a precursor to their consideration as the central component in analogue optical precision image registration systems. The exact meaning of the term "precision image registration" is articulated. At the very least, an analogue optical system should have the ability to variably magnify and rotate images if it is to have prospects of executing precision image registration. Motivated by this, an appraisal of various optical techniques of image rotation is undertaken. These investigations lead to an objective assessment of the feasibility of conducting precision image registration by suitably enhaced joint transform correlators. Qualitative comparison between analogue optical and digital electronic techniques of precision image registration, favours the lattter as the methodology for a practical system.
