The Polytec Inc. PSV-400-3D scanning laser vibrometer, utilized in experimental modal analysis, uses Doppler shift of back-scattered laser light to determine instantaneous velocity and displacement of ...

A key goal in several structural dynamics studies is to define the locations on a structure where failures are most likely to occur. Fatigue damage is a result of fluctuating strain. Therefore, it is ...

Using the Polytec PSV-3D Scanning Laser Vibrometer, Scientists at NASA’s Jet Propulsion Laboratory (JPL) have validated the dynamic response of spectrometer inlet funnels on the Mars Science ...

Laser vibrometry is used for research and diagnostics on the inner and middle ear. Vibrometers have also been used for measuring vibration on artificial heart valves to analyze vibrations during ...

Laser vibrometers consist of a low-power laser beam, picking up the signature of a vibrating object and transferring it into an output proportional to velocity and displacement that the researcher can ...

The Structural Dynamic and Acoustics Systems Laboratory is well equipped to conduct modal analysis, structural dynamic, acoustical, and control system experiments and modeling. Polytec 3D Scanning ...

ASDEC, a partnership between the University of Leicester and Polytec, to offer new robot-mounted R&D facilities for automotive and engineering systems designers. When it opens in May 2014, the ...
