Abstract
This paper describes a system based upon electronic speckle pattern interferometry (ESPI) for the measurement of in-plane radial strains on rotating specimens. Repeatable fringe patterns are obtained over a wide range of rotational speeds, and analyzed using the Fourier transform method. Radial strain data, extracted from the unwrapped phase fields, is compared with an established theory, and demonstrates a good agreement.
