Digital Scanning Laser Vibrometer Scan-Series

IMAGING VIBRATION MEASUREMENT

Scanning Laser Doppler Vibrometry is an advanced measurement technique for the visualization of vibrations on the sur-face of nearly any object. Scanning Laser Vibrometer can measure and visualize vibration shapes and eigenmodes, capt-ure the propagation of surface waves, validate FEM models, characterize vibration processes, and determine modal para-meters.

HIGHLIGHTSi

SWIR Scanning Laser Vibrometer

The Scan-Series combine the superior signal quality of SWIR laser vibrom-etry with the informative value of imaging methods by scanning the object under test on a flexibly definable point grid. Different measurement surfa-ces, wider coverage, and measuring ranges are the key to new fields of application.

Scanning vibrometry makes it possible to test entire workpieces automati-cally in one measurement process without contact or any influence on the object. Thus, scanning vibrometry enables the capture of local resonances and global vibration modes with the lowest effort.

• Excellent signal level

• Very compact

• Easy to operate• Highest accuracy and resolution
