Background of UDVDoppler ultrasound techniques were originally applied in the medical field over 30 years ago. The use of pulsed emissions extended this method to other fields and enabled new measurement techniques in fluid dynamics.
In pulsed Doppler ultrasound, instead of emitting continuous waves, the transducer sends short ultrasonic bursts periodically. A receiver continuously collects echoes reflected from targets present in the path of the ultrasonic beam.

2D/3D MeasurementsUDV 2D/3D ultrasonic measurements allow the simultaneous measurement of two or three velocity components along a line. One of the key advantages is the ability to obtain real-time measurements: only a few tens of milliseconds are needed to compute and display all velocity components.

The Ultrasonic BeamIn ultrasonic velocimetry, the shape of the ultrasonic beam is crucial. Ideally, the beam should remain as thin as possible throughout the measurement depth.
In the following pages, we explain some theoretical aspects of ultrasonic beam generation.
