Abstract:
Double-pulsed holography provides a measurement technique for the analysis of large surface areas of vibrating components. A particular advantage of holography is that it requires no contact with the vibrating object, and it gives a solution to a classical problem in the area of both acoustic and vibration analysis. The surface of a vibrating object is represented by a series of fringes which connect points that have equal amplitudes of displacement. Since holography is based on interferometry, the accuracy is within a fraction of the wavelength of light.
