Laser Doppler Anemometry (LDA)

Image of Constant Temperature Anemometry

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.
