A laser Doppler velocimetry apparatus was constructed complete with signal detection software in order to record accurate measurements for the frequency.

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

The objects can be microscopic particles in a fluid or solid surfaces—the concept is even used in some high-end laser mice. A period timing device suitable for processing laser Doppler anemometer signals has been described here. The important features of this instrument are: it is inexpensive, simple to operate, and A laser Doppler anemometer includes at least a first and second laser source, an optical system for directing laser beams from the sources to a specific region of a fluid flow containing particles in order to produce a virtual interference fringe pattern and at least one photodetecter positioned for receiving the scattered light from the flowing fluid. In this Laser Doppler Anemometer educational kit LDA CA-1350 Laser beams interact with small distortions on a rotating disc. Doppler-shifted scattered light causes a low frequency signal beating proportional to the velocity of the distortions.
