Laser vibrometry focusing on the small details

Characterize small and delicate structures in a non-contact way. Analyze vibration, acoustics and dynamics. Measure biomedical samples, electronics components and microstructures like MEMS by light, without mass-loading, and from DC up to the GHz range on a large bandwidth. Laser vibrometers focus on the small details, measuring deflection shapes for model validation. They assess the frequency response and determine resonance frequency, impulse response and Q factor. No matter how big or small – Polytec vibrometers measure it!

Vibration measurement in tight setups

VibroOne® is specifically designed for tightly packed setups, whether in research laboratories, challenging production environments or for non-contact analysis of tiny details on microstructures or biomedical probes. The optional inline HD+ camera helps positioning the laser precisely and provides proper test documentation. An optical filter adjusts for a perfect contrast of the laser spot. Optional microscope lenses focus to a 1.5 μm laser spot, even allowing the inspection of fine details. 

The all-in-one laser vibrometer VibroOne® allows measuring frequencies on a large bandwidth from DC up to 3 MHz with highest time resolution. The measurement system offers analog outputs for measuring displacement, vibrational velocity and acceleration synchronously. The digital VibroLink interface provides a convenient, fully digital transfer of the measured velocity signal via Ethernet to a notebook or computer. Thus it allows a comfortable and powerful analysis in time and frequency domain with the Polytec VibSoft data acquisition and analysis software with the best signal-to-noise-ratio (SNR). Thanks to its analog BNC signal outputs, VibroOne® is also compatible with conventional data acquisition hardware.
