Laser scanning vibrometry

[3][4] Fields where they are applied include automotive, medical, aerospace, micro system and information technology as well as for quality and production control.

They are also in widespread use throughout many universities conducting basic and applied research in areas that include structural dynamics, modal analysis, acoustic optimization and non-destructive evaluation.

The laser is scanned point-by-point over the test object's surface to provide a large number of very high spatial resolution measurements.

Vibrometry covers a huge range of applications such as the study of microstructures moving only a few pm at frequencies up to 2.5 GHz, all the way up to the intense dynamics occurring in Formula 1 engines with vibration velocities approaching 30 m/s.

A 3D scanning vibrometer combines three optical sensors that accurately detect dynamic movement from different directions in space in order to completely determine the 3D vectors of motion.
