A METHOD TO OBTAIN 3D IMAGES OF A FLOWING REGION BENEATH AN OBJECT USING SPECKLE REFLECTIONS

摘要

A method for imaging a flowing media within static regions includes obtaining a plurality of signals using the speckle properties of the flowing media. The plurality of signals are compared to one another such as by subtraction. Signals related to the static regions are suppressed by the comparison. The remaining signals are combined, such as by summing, to produce an image of the flowing media.
