Abstract
This paper describes the development of a hybrid Opto-electronic System that allows for the automatic extraction of displacement information from a sequence of holographic interferograms. The technique utilizes opto-digital image processing to determine the passage of fringes fOr a set of surface points simultaneously. Several of the notions included permit the fast and accurate quanti fication of displacement for large volunns of test data. The implementation of this technique will allow for the application of this relatively sophisticated non destructive testing method to the solution of traditional engineering mechanics problems.
