The use of fibre optics in laser Doppler velocimetry (LDV) promises increased versatility of the technique and novel optical designs. This paper discusses the properties of optical fibres and related components relevant to LDV design, and the likely limitations on system performance. The discussion is illustrated by descriptions of prototype systems constructed in these laboratories: a high power (~ 0.5 W) argon ion laser based system; a compact system incorporating a piezo-electric phase shifter to provide directional information; and a diode laser based system.
