A new class – for new ideas
VibroScan QTec measures vibrations in a new way – non-contact and with unprecedented precision. With its groundbreaking multi-path interferometry and diversity combining, QTec® sets new standards in terms of optical sensitivity and interference immunity. It determines operating waveforms and eigenmodes for NVH, acoustics, structural dynamics, ultrasound, FEM validation and non-destructive testing and offers frequency ranges up to 32 MHz. With its SWIR wavelength, the Xtra Laser brings more power to the measurement. This means that larger measuring distances are realized. The combination with QTec® makes the Xtra laser insensitive to the angle of impact and surface.
The VibroScan QTec Scanning Vibrometer ensures maximum portability. The VibroLink Ethernet data interface reliably transmits vibration measurement data to your notebook and serves as an automation interface.

Faster results with QTec® multi-path interferometry
The patented QTec® multi-path interferometer technology boosts the signal quality of infrared laser vibrometer (SWIR) decisively. It provides highest optical sensitivity for high-fidelity measurements on all surfaces, which significantly reduces testing time – even on dark, biological, rotating or moving objects. This safe laser technology is perfect for challenging applications also on distant targets. QTec® makes vibration measurements faster, easier and more reliable than ever – for the most robust, unambiguous results.
3D is as easy as 1D
Connect three stand-alone VibroScan QTec and measure the three-dimensional vibration vector. With three synchronous measurements from three directions, all three dimensions of the vibration open up for analysis.
The hub synchronizes two additional vibrometers with picosecond accuracy - MIMO-capable signal generators included. The PSV software takes over the guidance, detects the position of the individual VibroScans QTec in relation to the object, synchronizes the three laser beams and guides them over the measurement object in a μm-sized measurement spot. The results are automatically transformed into the FEM coordinate system and animated according to the direction of vibration.
