Surface Wave Measurement On Metal or Composite Using Polytec Laser Vibrometers

The phenomenon of surface wave measurement has attracted high interest in pure and applied research in recent years, the most recent relating to potential issues with HS2 (High Speed Rail Link). Lamb and Rayleigh waves travel rapidly across a structure in the region close to the surface. They present as a ‘rippling’ effect that can, at low amplitudes, tell the observer much about the integrity of that structure. For example, whether there ar...

Polytec Presents New High Frequency Vibrometer – UHF120

This new laser Doppler vibrometer features a frequency range up to 1200 MHz. Designed for the characterization of high frequency dynamic behaviour of micro components and HF transducers. Investigating the dynamics of micro components, such as MEMS (Micro-Electro-Mechanical System), new transducer technologies and new combinations of micro- and nanotechnology with ultrasonic actuation, engineers need new methods and instruments for characterizing ...
