Digital Scanning Laser Vibrometer Scan-Series HeNe Scanning Laser Vibrometer Scanning Laser Doppler Vibrometry is an advanced measurement technique for the visualization of vibrations on the surface of nearly any object. Scanning Laser Vibrometer can measure and visualize vibration shapes and eigenmodes, capture the propagation of surface waves, validate FEM models, characterize vibration processes, and determine modal parameters. HIGHLIGHTS • Excellent signal level • Very compact • Easy to operate • Highest accuracy and resolution • High-speed vibrations up to 10 m/s IMAGING VIBRATION MEASUREMENT The Scan-Series combine the superior signal quality of HeNe laser vibrometry with the informative value of imaging methods by scanning the object under test on a flexibly definable point grid. Different measurement surfaces, wider coverage, and measuring ranges are the key to new fields of application. Scanning vibrometry makes it possible to test entire workpieces automatically 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
