Abstract:

Holographic measuring techniques combined with the speed and convenience of video recording and display, provides a real-time system which can be used to reveal extremely small movements. By various excitations like heating, pressure and vibrations we detect object defects and structural weaknesses. In this paper we describe the systems construction, its modes of operation and discuss its potentials. Finally we give some examples of the applications of the system.
