Laser vibrometry and the secret life of speckle patterns

Speckle patterns are produced when coherent light scatters from optically rough surfaces. In typical applications, a Laser Vibrometer collects a region of a speckle pattern on its photodetector. However, noise can be generated in the Laser Vibrometer output when surface motions cause changes in the...
