Abstract

A method for processing signal from laser Doppler anemometers using wavelet-transformation is reviewed The errors of an estimation of particles velocity, obtained by analysis of a wavelet-spectrum of the LDA signal, are calculated. The influence of anemometer and signal parameters on measurement enors is examined. Guidelines for measurement technique are provided.
