An experimental technique which combines the accuracy of holographic interferometry and the ease of a television video display which may be used under service conditions for in-plane strain measurement is extremely attractive. Electronic Speckle Pattern Interferometry (ESPI) is a technique which displays this potential and development for application to rotating structures is at present taking place at The City University. The latest results achieved showing interference fringes recorded at tangential velocities up to nearly 5 ms-1 are presented.
