Abstract

A comparative study between several full field optical techniques for the visualization of the vibrational modes of aero engine components is presented. The methods considered are holography, electronic speckle pattern interferometry (ESPI) and laser Doppler velocimetry. The relative merits of each technique are assessed with regard to their application in an industrial environment.
