Amplitude and frequency as key indicators for quality control
Optical measurement technology helps ensure the quality of acoustics and vibration characteristics both in development and on the production line. Laser vibration measurement technology measures amplitudes independently of frequency, quickly and reliably. Scanning vibrometry, in particular, allows area-based and non-contact amplitude measurement and is commonly used in research and product development for FE model validation, prototype testing or design optimization. However, it can also be used to derive suitable measurement points for a subsequent targeted 100% inspection in production in order to reliably detect rejects in production. Scanning vibrometry is also an efficient production measurement technique when multiple measurement points or the full-field amplitude distribution need to be checked.
