The second Laser Doppler Anemometer - LDA


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. Science and industry apply 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.

Features: Non intrusive. No calibration required. Velocity range 0 to supersonic. One, two or three velocity components simultaneously. Measurement distance from centimeters to meters. Flow reversals can be measured. High spatial and temporal resolution. Instantaneous and time averaged.
