Single-point vibrometers measure the amount of vibration at a single point on an object's surface. More specifically, a laser vibrometer measures the projected component of an object's surface vibration vector along the direction of the incident laser beam. For example, if aligned perpendicularly to surface under test, the vibrometer measures the out-of-plane vibration to the surface (the instrument is sometimes referred to as an out-of-plane vibrometer).Measuring the Dynamic Response of Solar Panels (180KB)
Polytec scanning vibrometers make vibration measurement and analysis simple and efficient.
Tell us about your structural vibration measurement task and we'll provide the scanning vibrometer solution for frequencies from DC up to 24 MHz and vibrational velocities of 0.02µm/s up to 20m/s.
As your requirements expand, you can upgrade and enhance your vibrometer step by step. Choose between 1-D (out-of-plane) systems, e.g. for sound radiation measurements, or 3-D vibrometers (complete vibration vector) which provide a three-dimensional data set for conducting modal analysis. For microstructures, we recommend our Micro System Analyser (MSA).Scanning Vibrometer Press Release (77KB)

Inspired by the growing variety of Microelectromechanical systems (MEMS), Polytec has developed an innovative line of microscope systems for the measurements of MEMS dynamics and topography.
The MSA-500 Micro System Analyser is the premier, fully-integrated, measurement tool for the analysis and visualisation of structural vibrations and surface topography in micro structures. For wafer-level testing, all systems can easily be mounted onto manual or fully automated probe stations.Send Enquiry
Understanding the origin of the stress and strain distribution is crucial to increasing the durability of components under dynamic load. Numerical simulations based on finite element (FE) models help with this understanding but must be validated by real component data. Polytec's 3-D Scanning Laser-Doppler Vibrometer with StrainProcessor provides an advanced, non-contact optical test solution.
Polytec's StrainProcessor is a measurement extension developed for easy FE
The Scanning Vibrometer makes a series of non-contact deflection measurements on a predefined grid using the laser probe to characterise strain at each point instead of attaching individual strain gauges. Thus, the test set-up is fast and very repeatable with no mass loading from an attached transducer. Tests are fast and avoid the high cost of preparing and instrumenting the sample with strain gauges.Send Enquiry
Polytec software provides powerful tools that control the measurement, process data, provide intuitive and animated data visualisation and interface with third-party software for modal analysis, FEM
Each application is unique, each measurement is important, each set-up must be correct. Polytec has engineered convenience and flexibility into their accessories to facilitate the use of your vibrometer and its adaptation to almost any measurement application. Designed correctly, these accessories assure a firm support of your sensor head, provide proper illumination in microscope set-up, and enhance measurement surfaces where reflected signals are weak.
