Polytec vibrometer awarded for outstanding innovation

Polytec has revealed that its UHF-120 Ultra-High Frequency Vibrometer was awarded the 2011 Industry Prize for outstanding innovation in the category of microsystems engineering at a recent Hannover Messe trade show.

The UHF-120 captures high-frequency vibrations and transient motion processes by optical Doppler interferometry. The instrument can be applied to completely new applications due to its ability to measure frequencies up to 1.2GHz (50-times higher than conventional vibrometers). The UHF-120 provides direct optical measurement and subsequent motion visualisation of novel microelectromechanical and microelectronic devices, such as RF-MEMS (as used in mobile phones), NEMS, ultrasonic transducers (as used in medical devices), or SAW and BAW filters.

The visualisation method is comparable to a camera, capable of resolving minute vibration amplitudes of less than 1pm, and ultra-high-frequency motions of up to 1.2GHz. Development engineers can use the device to characterise the mechanical properties of new devices easily and precisely, leading to better products and shorter development cycles.
