With three synchronous measurements from three directions, all three dimensions of the vibration open up for analysis. The hub synchronizes the 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 measuring spot. The results are automatically transformed into the FEM coordinate system and animated according to vibration direction.

VibroScan QTec Xtra 3D determines operational vibration modes 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. The combination with QTec® makes the Xtra laser insensitive to the angle of impact and surface, making it ideal for 3D measurements. The VibroLink Ethernet data interface reliably transmits vibration measurement data to your notebook and serves as an automation interface.

With the new VibroScan QTec, we are taking reliability, flexibility and speed in non-contact vibration measurement to a whole new level. In this webinar recording, our expert Jörg Sauer takes you into the world of groundbreaking QTec technology and the new VibroScan QTec for your modal analysis, acoustic and NVH measurements, operational vibration analysis and product development. 

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.
