Laser vibration sensor VibroFlex

opticalfiber opticfor small spaces

VibroFlex is a modular vibration sensing system for non-contact vibration measurement covering applications from microscopic structures to large and distant objects. The family combines multiple dedicated laser sensor heads with the Connect+ front-end and VibSoft software to provide flexible, high-performance vibration measurements for R&D, production testing and quality assurance.

Key features

• Modular concept: interchangeable sensor heads to match application needs (microscopic to long-range).
• Configurable bandwidth from DC up to 32 MHz.
• Extremely high sensitivity: sub-picometer displacement resolution.
• Velocity capability up to ±30 m/s.
• Supports fiber-optic sensor heads for access to confined or hard-to-reach locations.
• Differential optics for direct relative-motion measurements between two points.
• Integrated camera for precise laser positioning and test documentation.
• Designed to measure reliably on challenging surfaces (dark, oily, shiny, hot) without surface preparation.

Connect+ front-end (core unit)
Phase-synchronous reference acquisition, encoder/tacho inputs for order analysis and run-ups, integrated signal generator for transfer function measurements, and PTP-synchronized multi-vibrometer setups. Ethernet and WiFi connectivity for measurement data transfer and control (VibroLink).

Sensor head family (examples)

• VibroFlex Xtra Fiber — remote fiber-optic head for demanding or embedded environments.
• VibroFlex Fiber — fiber-optic head for flexible access and phase-stable relative measurements.
• VibroFlex Compact — compact head for confined test setups and microscope objectives for microstructure analysis.
• VibroFlex Neo — high-resolution head for measurements through transparent media (glass, water) and climate-chamber testing.
• VibroFlex QTec — QTec® multi-path interferometer head for best signal-to-noise on shiny, oily or rotating surfaces.
• VibroFlex Range — long-distance head for remote measurement (ranges > 500 m) on large structures and hazardous areas.

Software & workflow
VibSoft provides data acquisition and analysis optimized for laser Doppler vibrometry; VibroLink enables digital data transfer (Ethernet/WiFi/TCP-IP) and integrated workflows. The system supports synchronous outputs of displacement, velocity and acceleration for analysis in time and frequency domains.

Applications & benefits

• Research & development: full bandwidth and high time resolution for modal and transfer-function analysis.
• Production testing & QA: fast, non-contact, wear-free inspection and pass/fail decisions.
• Field and long-range measurements: remote monitoring of structures and machinery.
• Confined-space & microscopic testing: fiber-optic access and microscope objectives.
