Abstract

A system for assessing the flow of a fluid. The system can include a light source, a fiber-optic system optically coupled to the light source, which is arranged to provide a reference beam and an observation beam, an optical detection system arranged to receive combined light from the reference beam and the observation beam and to provide detection signals, and a data processing system arranged to communicate with the optical detection system to receive the detection signals. The data processing system can be configured to use the detection signals to determine a speckle pattern corresponding to the fluid flow, wherein the speckle pattern includes a plurality of lines, and to calculate a correlation between adjacent lines perpendicular to the flow to determine at least one of a rate of the flow and a displacement of the flow.

First claim

We claim:

1. A system for assessing the flow of a fluid, comprising:
a light source;
a fiber-optic system optically coupled to said light source, said fiber-optic system arranged to provide a reference beam and an observation beam;
an optical detection system arranged to receive combined light from said reference beam and said observation beam, said optical detection system providing detection signals; and
a data processing system arranged to communicate with said optical de…
