Abstract of the Disclosure A laser Doppler anemometer with at least two laser beams pass to a region of a fluid flow containing particles. The scattered light is frequency shifted by the Doppler frequency resulting from the flow speed. The construction is very compact and permits a high signal-to-noise ratio for the measurement signals. The laser beams consist of high-frequency pulses, the frequency of the pulse sequence of which is a multiple of the Doppler frequency.
