Scanning-Vibrometer

Scanning laser Doppler vibrometry is a high-speed imaging measurement method for the visualization of vibrations. Scanning laser Doppler vibrometers (SLDV) from OptoMET work on the non-contact measuring principle and provide precise insights into the dynamic behavior of vibrating structures. They can find and visualize vibration modes and eigenmodes, capture the propagation of surface waves, validate FE models, characterize vibration processes and determine modal parameters.

Imaging vibration measurement

The Scan Series combines for the first time the superior signal quality of SWIR laser vibrometry with the informative value of imaging methods by scanning the objects 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 and without influence on the object and to capture local resonances and global vibration modes with low effort.

The acquired measurement data can be visualized by means of the analysis software over time and frequency as well as in the form of three-dimensional animations.

Available decoders

A wide variety of high-performance real-time decoders are available for the evaluation of the interferometric measuring signals. The OptoMET UltraDSP technology enables the measurement of frequencies up to 10 MHz (for Single-Point Operation Mode) and vibrational velocities up to 24.5 m/s, displacements can be resolved to less than 100 fm. All vibrometers incorporate a velocity decoder, and displacement and acceleration decoders are optionally available. Numerous measuring ranges per decoder ensure that measurements can always be performed with the optimum sensitivity.

Decoders can be easily retrofitted or upgraded. Start with a basic system and adapt the capabilities of the measuring instrument as required. This requires no return of the instrument to the factory and no waiting times for your production or research project. The table below provides an overview of the configuration options. We will also be happy to assist you in the selection of the best decoder for your measuring task.
