Areas of Vibrometer Applications

Vibrating components and structures are a key area of concern in the automotive and aerospace industries
and in many other fields of application.

Laser Doppler Vibrometry (LDV) is well established as a fast, efficient and cost-effective means of measuring and analyzing the extent of a structure's vibration. Not only is no contact made with the part under investigation but, due to the high optical sensitivity of the Ometron sensors, the measured surface does not need to be specially modified or prepared in advance. However, it is not just in vibration reduction that Ometron Laser Doppler Vibrometers are being used. Increasingly, the instruments are finding a new role in quality control. Examining the resonance characteristics of a metal casting, for example, can indicate whether the component has been machined correctly.

Laser Doppler Vibrometry sensing is a robust technique for the measurement of mechanical vibration without surface contact. LDV integrated with FFT analysis is a well established technique in the development laboratory of the automotive and aerospace industries, but has also other applications.

Its potential to provide an accurate dynamic picture of the quality of products as diverse as traditional machined parts and electronic components and assemblies is rapidly finding it a place in the quality control armory of many major manufacturing companies.
