Paper Abstract

A pulsed ESPI laser for measuring in-plane displacements and strain on rotating components is shown to operate in a very wide range of component speeds and tangential velocities. An optical system based on fiber optics techniques in conjunction with an infrared diode laser can provide clear interface fringes for radial displacements on a rotating component at tangential velocities up to 150 m/s.
