Abstract
We present an outline of vibration analysis techniques that we have used recently which are based on video speckle interferometry. The work described is carried and deals with the following subjects: the determination of composite vibration induced strain, with the use of both (a) speckle shearing interferometry and (b) electronic speckle pattern interferometry (ESPI); (c) two mode vibration analysis based on stroboscopic ESPI and (d) inexpensive techniques for multimode vibration analysis based on hybrid ESPI and laser velocimeter measurements.
