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)

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.
Polytec is addressing the surface metrology market with innovative, high-precision 3-D profilometer technology that works on rough, smooth and stepped surfaces without contact. These products are based on scanning white-light interferometry, also called coherent or vertical scanning interferometry or coherence radar. With their large vertical range and nanometre resolution, they are ideal tools for determining flatness, height differences and parallelism of large surfaces and structures, including soft materials.Send Enquiry
Hard disk drives are manufactured with nanometre precision. The slightest change in manufacturing can cause surface roughness variations large enough to cause failures in the field. For the best yields it is necessary to optimise your process. Measuring and understanding the characteristics of your product allows continuous improvement.
The AVT-1000 Advanced Vibrometry Tester enables you to measure all critical parameters such as roughness, waviness, and defects across the whole surface of the sample providing important information for process optimisation. No other technique can give you such precise, quick, and full surface measurement results.Send Enquiry

The UHF-120 Vibrometer can characterise the out-of-plane vibrations at ultra-high frequencies, extending the vibration frequency bandwidth up to 1.2GHz. Complete with a new optical design, the instrument retains the advantages and features familiar to laser vibrometer users.
The system consists of a heterodyne interferometer with a controller box. The optical head provides a heterodyne detector signal that is acquired with a fast digital oscilloscope. The digitized detector signal is transferred to a PC where the heterodyne carrier is demodulated by a new software module in Polytec's Vibsoft package.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
