Technology and laser-based measurement solutions company Polytec, based in Germany, received the 2011 Industry Prize at this year’s Hannover Messe trade fair for its ultrahigh-frequency-120 (UHF-120) vibrometer.
The prize was awarded by publishing house Huber Verlag für neue Medien for outstanding innovation under the Microsystems Engineering category.
The UHF-120 captures high-fre- quency vibrations and transient motion events using optical Doppler inter-ferometry.
The instrument can be applied to new research and development owing to its ability to measure frequencies up to 1.2 GHz, which is 50 times higher than conventional vibrometers.
It provides direct optical measurement and subsequent motion visualisation of novel microelectromechanical and microelectronic devices, such as those used in mobile phones and medical devices.
The visualisation method is similar to that of a camera, capable of resolving minute vibration amplitudes of less than one phase modulation, and UHF motions of up to 1.2 GHz.
The development engineers can now characterise the mechanical properties of a new device simply and precisely, leading to better products and shorter development cycles.
The system has a gate function for reducing light power to minimise energy transfer from the measurement beam to the measurement spot, and for easy alignment of the beam on the specimen.
Polytec also won the Innovation Award of the German Economy for its RoboVib Structural Test Station, in 2009, as well as the MessTec & Sensor Masters Award for the Optical Derotator.
