Laser Doppler 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.
Science and industry apply 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.

|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|
