Paper Abstract

The performance of an optical system can be specified by the OTF or by means of a new method employing pupil-scan-ning Whilst the former technique is most suitable when an image is transferred through a chain of units operating in sequence, the latter system, was developed for testing high performance trackers for which a maximum of energy concentration is required. Instruments for measuring the OTF, displaying spot diagrams, transverse ray aberrations and wavefront aberrations, are compared and contrasted. The performance characteristics of typical image transfer systems such as microscope lenses, process lenses, IR trackers and fibre face plates are presented by way of example. All the techniques described have been developed over the last ten years to satisfy the special requirements of both manufacturers and users of electro-optical systems.
