Abstract
Apparatus and method for measuring fluid velocity in a conduit or in open space comprises providing a laser which sends a beam through the fluid, measuring how the beam deflects due to the effect of transverse-moving fluid on the beam, and calculating velocity based on the deflection. The laser beam is one which causes thermal blooming within the fluid and that causes the beam to deflect as a function of the velocity of the fluid. The beam deflection is directly or indirectly measured, for example by looking at the movement of a beam spot on a target, or by sensing the change in intensity of the beam at a target.
