Abstract

A real-time reflective holographic interferometry system is described. It overcomes the vibration isolation problems associated with conventional real time holography, and presents living-fringe patterns which can give dynamic deformation maps of an object under study. Two set-ups used to produce real-time reflective holographic interferograms are presented. Its optical arrangement is very simple, comprising a low-cost C.W. laser (10mW He-Ne), a shutter and a spatial filter mounted on a camera tripod. This real-time technique is applied to measure the local buckling of a riveued lap joint.
