Abstract

An electronic speckle shearing interferometer, or TV shearometer, characterized by a very small shear, has been used to measure the exact vibration amplitude derivative of a vibrating object. The technique is based on a heterodyne speckle shearing interferometer and uses fringe analysis methods appropriate when less than one fringe is observed on the vibrating object.
