Multi-path vibrometry weights receive channels into a stable signal with the best signal-to-noise ratio – diversity combining DATA ACQUISITION AND ANALYSIS SOFTWARE Intuitive: 3D deflection shapes in minutes Self-explanatory: the PSV software CAE integrated: virtual measuring Future-proof: open architecture

■ Highly stable vibration signal ■ High signal-to-noise ratio ■ Shorter measurement time ■ Precise data acquisition ■ Suitable for all surfaces and environments

What is QTec®? Polytec's QTec® technology revolutionizes laser vibrometry through multi-path interferometry with diversity combining. By using independent detection channels, QTec® captures the signal from different perspectives simultaneously resulting in a stabilized signal and a high signal-to-noise ratio. Cause of noise A single receive channel sees a speckle pattern that fluctuates over time. Dark speckles lead to noise, bright speckles contain the full useful signal. With a QTec® interferometer, the pattern is different in each channel and the probability of a dark speckle decreases significantly...

Our technological edge for your application QTec VibroScan QTec Neo r The precise helium-neon laser is suitable with its small laser measuring spot for measurements on the finest structures and even measures in and _ through water and other transparent media. ..

VibroScan QTec Xtra With its SWIR wavelength, the Xtra laser brings more power to the measurement. This makes it easy to realize larger measuring distances. The combination with QTec® makes the Xtra laser incident to the angle of impact and therefore ideal for 3D measurements. BEST SIGNAL QUALITY AT ANY DISTANCE TECHNICAL SURFACES HIGH VIBRATION VELOCITIES UP TO 30 M/S

Software: one ecosystem – many possibilities Simply combine the VibroScan components with each other and synchronize them with picosecond precision. If required, you can integrate single-point vibrometers as reference vibrometers via the central PSV software. One software for everything – PSV Software Controls all vibrometers S ynchronizes the phase position Integrates all measurement data to the analysis Interface to CAE and external analysis tools

Software: push forward into new dimensions! Scanner, camera and data acquisition measure and visualize every vibration shape precisely from the direction of the laser beam. If the measurement object or vibration is complex, only the three-dimensional vibration vector provides complete information. You are always prepared for this in the VibroScan ecosystem. Connect three stand-alone VibroScan QTec sensors to the hub and measure the three-dimensional vibration vector. With three synchronous measurements from three directions, all three dimensions of the vibration open up for analysis.

3D is as easy as 1D The hub synchronizes two additional vibrometers with picosecond accuracy. MIMO-capable signal generators included. Automatic Alignment The PSV software takes over the guidance, recognizes the position of the individual VibroScans QTec in relation to the object, synchronizes the three laser beams and guides them in a µm-sized measuring spot over the measured object. The results are automatically transformed into the FEM coordinate system and animated according to the direction of vibration.
