Non-contact vibration measurements with laser vibrometry

Laser Doppler vibrometry (LDV) or laser vibrometry is an optical and therefore non-contact measurement method. As the name suggests, the method is based on the principle of the Doppler effect and interferometry.

As a result, laser vibrometry – in contrast to measurement with acceleration sensors – has no effect on the vibration behavior of the object being measured.

It is therefore ideal for vibration measurements on the smallest components, for example on printed circuit boards or individual coil wires. It can also be used to measure in hard-to-reach places and inside objects. The laser vibrometer only requires optical access, e.g. an opening in a housing.

Vibration analysis at Vibtec with the laser vibrometer

We have been successfully using various laser vibrometers from Polytec for vibration testing for many years. They can be used flexibly for a wide variety of tasks, for example:

for modal analysis with vibration excitation using an impact-hammer
for vibration measurements on electro-dynamic and hydraulic shakers at our premises
or also on your premises.

A description of the various laser vibrometers we use can be found on the laser vibrometer page.
