Real-time holographic interferometry is a viable technique to determine surface displacement of prototype mechanical components placed under load. Six funded consulting projects have been completed in the GMI Holography Laboratory during 1985. A thermoplastic holographic camera-is used to record the holograms and a videotape system for documentation. Holographic system geometries are used to reduce the equations used for data analysis to a simplified form. Conventional holographic techniques are used to determine displacement magnitudes and a carrier fringe technique is used to determine displacement directions. Efforts are being made to make holographic analysis as simple and efficient as possible to respond to industrial needs.
