Laser-Based Flow Measurements to Evaluate Hydraulic

When a particle or microscopically textured surface move through this region, it reflects bursts of light corresponding to its passage through the regions of constructive interference. Laser Doppler Anemometer (CA-1350) Laser Doppler Anemometry is a contactless technique for the measurement of velocities. Its principle is based on the phenomenon of the Doppler frequency shift of (Laser) light scattered by moving particles. This frequency shift is directly related to the velocity of the particles, and hence A Laser Doppler Velocimeter (LDV), also known as a Laser Doppler Anemometer (LDA), is a type of interferometer that measures the velocity of objects using laser light.

The liquid flow starts developing from the sparger where non-uniformities in the gas sparging exist. From z A laser-doppler-anemometer of the kind in which a radiation beam (a) having a predetermined direction of polarization emitted from a laser (1) is separated into two spatially distinct partial beams (B, C), one of which is led through a frequency displacement device (3), following which the separated frequency-displaced partial beams (B, C') having the same direction of polarization are LDA - Laser Doppler Anemometer.
