Using cutting edge laser sources and interferometry, Optomet Laser Doppler vibrometers enable the non-contact measurement of vibration over a range of several orders of magnitude, from atomic dimensions all the way to large buildings.
Easy measurements on virtually any kind of surface and without any influence on the sample are an indispensable tool for the analysis of even the most delicate structures. Optical laser doppler vibrometry uses the principle of a Mach-Zehnder Interferometer, which shows any changes in the measurement beam due to the frequency shift induced by the doppler effect when the laser light of the measurement beam is reflected from a vibrating surface. A detailed explanation of how a Laser Doppler Vibrometer works can be found at Measurement Principle.
For a wide variety of applications in industry and research, Optomet consequently utilizes advanced and user-friendly Laser Doppler vibrometers that meet highest technical standards while being easy to operate.
