A laser-Doppler anemometer based on a continuous GaAlAs diode laser source is described. It is shown that the coherence length of the diode output requires that the optical design incorporate equal path lengths for good fringe visibility. The results show that Doppler signals of processable quality may be obtained using this compact laser source
