Laser Doppler Anemometry (LDA), also known as Laser Doppler Velocimetry (LDV), is an optical technique ideal for non-intrusive 1D, 2D, and 3D point measurement of velocity and turbulence distribution in both free flows and internal flows.
Researchers in science and industry use our LDA systems to gain a clearer understanding of fluid mechanics. The measurement results are important steps in fine-tuning product designs to improve aerodynamic efficiency, quality, and safety.
Measurement Principle
The Laser Doppler Anemometer, or LDA, is a widely accepted tool for fluid dynamic investigations in gases and liquids and has been used as such for more than three decades.
