Abstract

Flows study methods by selecting of the spatial-temporal structure of the scattered light are discussed. The Doppler anemometry with adaptive spatial-temporal selection and visualization of velocity vector resides in communicating the measurement channels on line with discretization of the process by a flow of scattering particles. As a result it makes it possible to increase considerably an energy flow density in a probing field under the same laser radiation power. A color visualization of optical density fields in real time based on polychromatic Foucault-Hilbert transformation is described.
