Paper Abstract

Modified holographic interferometers are described which enable automatic fringe pattern analysis to be achieved when recording transient events. The introduction of a phase grating enables the method of phase-stepping fringe analysis to be applied to a wide range of metrological problems. The theory of three- and fourchannel holographic interferometers is developed and an analysis of the sources of error is presented with the aid of computer simulations. The adjustment procedure and initial experimental results are shown to confirm the utility of the systems.
