The faster the moving source of sound, the greater the shift in frequency. This effect is also observed with light. A laser Doppler anemometer measures the velocity at a point in a flow using light beams. It senses true velocity component, and measures that component in a sequence of near instantaneous samples. This research demonstrates the capability of the Laser Doppler Anemometer (LDA) for making measurements inside a piston-engine cylinder. The backscatter mode of LDA operation, requiring only a single window in the cylinder, was used. An ensemble-average data-processing technique has been developed to analyze the raw velocity-crankangle data.

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 objects can be microscopic particles in a fluid or solid surfaces—the concept is even used in some high-end laser mice.

The major limitation of the set-up used was the time required to move the anemometer and obtain a new velocity value. Operation of Laser Doppler anemometer 1. The laser source sends a beam that is divided by a beam splitter into two beams. 2. The two parallel beams are focused by lens L1 so that they intersect at a point in the test section where there is 3.

A rapidly scanning directionally sensitive fringe-type laser Doppler anemometer (SLDA) which scans the measurement volume perpendicular to the optical axis of the transmitting optics is described.

The particles (carried along with the flow) that pass Modern laser Doppler anemometer systems incorporate a Bragg cell for frequency shifting of a laser beam, at a frequency of 40 MHz, in order to remove any directional ambiguity.
