Laser Doppler Anemometry (LDA)

Laser Doppler Anemometry (LDA) or Laser Doppler Velocimetry (LDV)

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 Laser Doppler Anemometry (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.
