Advances in Ultrasonic Measurements Using Laser Doppler Vibrometry

摘要

Laser Doppler Vibrometry is a widely used technique to examine ultrasonic waves in solids, liquids and gases. The main advantages using a Laser Doppler Vibrometer in the field of ultrasonic measurements are the constant sensitivity over a very wide frequency range, the non contact measurement and the high spatial resolution. Different application examples prove the high performance of this measuring technique. Finally the properties of new high-performance Ultrasonic-Laser-Doppler-Vibrometer systems will be discussed and new applications will be pronounced.
