Abstract
A novel method for directional multicomponent laser Doppler anemometry , based on the generation of different carrier frequencies, one for ea ch velocity component, is presented. The laser frequency modulation in conjunction with fiber delay lines of different lengths generates the carrier frequencies without involving additional frequency shift elem ents, so that a simplified laser Doppler anemometer can be realized.
