Anemometer, Doppler, Basic
Wednesday, August 30, 2006
A Doppler Laser Anemometer has been designed and developed consists of a laser light source, focusing optics, receiving optics, a photodetector, and a photodetector signal data microprocessor. The microprocessor processes the Doppler Frequency Shift of the detected signals to determine the particle flow stream velocity. Individual particles in a flowing particle air stream will scatter the laser light beam. The movement of particles will cause a Doppler Frequency Shift in the laser light beam. The Doppler Frequency Shift detected signals are used to calculate the velocity of the particle stream.
The Doppler Laser Anemometer requires no mechanical probe sensor. A probe sensor could interfere with the detected signal accuracy. The non-use of a probe sensor also allows for measurements to be collected in hostile environments. The laser light beam can be focused to change the examination spot size within the flowing particle air stream and not disturb the flow stream configuration.
