Paper Abstract

An experimental technique of in-plane strain measurement on large rotating structures in service, requiring only minor surface preparation and little or no interruption to or shut-down of costly production-line plant is extremely attractive. The development of ESP1 (electronic speckle pattern interferometry), which displays this potential, using a pulsed laser is described. Some preliminary results for component tangential velocities up to 3.4 ms-1 are presented.
