Scanning Vibrometers

 

Polytec offers a comprehensive line of scanning laser Doppler vibrometers (SLDV). Scanning offers all the advantages of a laser vibrometer together with speed, ease of use, laser positioning accuracy and comprehensive data processing in a single automated, turnkey package.

Users get a very quick, easily understood and accurate visualization of a structure's vibrational characteristics without the inconvenience of attaching and interpreting data from an array of transducers.

An SLDV includes one or three compact scan heads, data management system and powerful software for control of the scanners, data processing and display.
