MEASUREMENT OF VIBRATION BY HOLOGRAPHY

The application of holography to the vibrational measurement on engineering components is described together with its advantages over the usual sand pattern and contact probe methods. The time averaged fringe holographic technique has been used to study aero engine compressor blades, turbine discs and shaft assemblies. Holographic interferometric methods of real time vibration analysis, to quickly obtain some information on a number of vibration modes, are discussed. The practical requirements and equipment for holography are studied and the development of a completely self contained holographic unit that has been designed specifically for vibration measurements on components up to 2 ft diameter, is described.
