Measurement of high-frequency speckle vibration amplitude from a blurred image

The non-contact detection of a vibrating surface through the extraction of the vibration of the speckle pattern that the surface produces when illuminated by a coherent source of light has been implemented almost from the invention of the laser and is still an active field of research. In this work,...
