Ultrasonic Doppler Velocimetry

Background of UDV

Doppler ultrasound technique, was originally applied in the medical field and dates back more then 30 years. The use of pulsed emissions has extended this technique to other fields and has open the way to new measuring techniques in fluid dynamics.

In pulsed Doppler ultrasound, instead of emitting continuous ultrasonic waves, an emitter sends periodically a short ultrasonic burst and a receiver collects continuously echoes issues from targets that may be present in the path of the ultrasonic beam.....

2D/3D measurements

UDV 2D/3D ultrasonic measuring technique is a method that enables the measurement of two or three velocity components simultaneously along a line. One of the most interesting property of this technique is its capability to get real time measurements. Only few tens of milliseconds are necessary to compute and display all velocity components.

The ultrasonic beam... a key point

In ultrasonic velocimetry, the shape of the ultrasonic beam has a great importance. Generally an ultrasonic beam as thin as possible throughout the measurement depth is desired.

In the following pages we will offer you some theoretical aspects of the generation of the ultrasonic beam.
