Paper Abstract

In laser velocimetry, flow velocities are deduced from the frequency of the light scattered by microparticles transported by the flow and seen through a fringe pattern. This frequency being independent of the sign of the velocity, this sign can be determined by moving the fringe pattern : this operation makes use of acousto-optical modulators which change the frequency of the laser beams interfering in the probe volume. A general discussion of this method compared to other possibilities is given in this paper.
