Laser Doppler anemometry
Abstract
A brief survey is given of the principles and present state of the art in laser Doppler anemometry. Both the optical and signal-processing aspects are treated in some detail. The comparative features and special problems associated with the various methods of interpreting the Doppler signals are discussed, with particular reference to the more recently developed technique of photon correlation. A wide range of practical applications, including measurements on liquids and solids, is considered.
