Pulsed laser ESPI provides a non-contact method of in-plane strain measurement on rotating components. Engineering problems over a wide range of speeds up to 12,500 r.p.m. and tangential velocity of 150 ms-1 may be analysed. Illumination via optical fibres removes the problem of components with limited optical access.
