Abstract: A laser method for three-dimensional measuring the velocity vector is discussed. In this method, a three-beam configuration of the probing field is used to form a 3-D orthogonal coordinate basis. The method has been realised in an operating prototype of the measuring system that employs temporal selection of the velocity components. It has been tested experimentally in a study of a swirling flow.
