Laser Interferometer

Laser Doppler Vibrometer

Laser Doppler vibrometry is an optical technique for non-contact measurement of vibrations. Modern laser doppler vibrometers (LDV) record mechanical vibrations with highest accuracy. No other technology available comes close to Laser Doppler Vibrometry in terms of frequency bandwidth, sensitivity and resolution. Thus, vibrometers are the unbeaten instrument of choice when it comes to fast and accurate vibration measurements.
