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...

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.
