Abstract

The temporal fluctuations in the laser speckle pattern produced by scattering from moving objects obey the same statistics as the spatial variations of the stationary speckle pattern. These statistics can be used to measure the movement of the scattering particles, a technique of particular value in biomedical science. Potential applications include monitoring blood flow, motility, and intra-cellular activity.
