ABSTRACT:
The multiple measuring control volume laser Doppler anemometer includes a laser for providing an optical beam. The beam is transformed by an optical arrangement to produce a number V of measuring control volumes wherein each control volume has two focussed optical beams intersecting at a unique predetermined angle .phi.. A detector collects the scattered light from the measuring control volumes in order to determine the velocity at each of the control volumes.
