Capillary Blood Flow Monitoring Using Laser Speckle Contrast Analysis (LASCA) Open
Coherent light scattered from an ensemble of moving scatterers produces a time-varying speckle pattern. The intensity fluctuations observed in a single speckle can be regarded either as a time-varying interference effect or as a Doppler be…
Laser speckle contrast analysis (LASCA): a nonscanning, full-field technique for monitoring capillary blood flow Open
A new noninvasive technique for monitoring capillary blood flow has been developed. Based on the phenomenon of time-varying laser speckle, it is a digital version of single-exposure speckle photography. It provides a velocity map of the ar…
