Vibration analysis with young's fringes modulated speckle

Bolognini, Néstor | Rabal, Héctor J. | Garavaglia, Mario J.
Abstract: A new method for vibrational analysis is proposed. It is based on the deblurring of time-averaged Young's fringes inside speckle grains in the image of a vibrational object. A spatial filtered image of the recording of those speckles, modulated by Young's fringes, shows the loci of points of equal v...
Abstract: A new method for vibrational analysis is proposed. It is based on the deblurring of time-averaged Young's fringes inside speckle grains in the image of a vibrational object. A spatial filtered image of the recording of those speckles, modulated by Young's fringes, shows the loci of points of equal vibratory amplitude.
