Fiber-optic Vibration & Displacement Sensor

Product Announcement from MTI Instruments Inc.

Fiber-optic Vibration & Displacement Sensor-Image

The MTI-2100 features advanced fiber-optic and electronic technologies for precise measurements of displacement, position and vibration. It sets new performance standards with resolution up to 0.01 µin. (2.5 Angstroms) and frequency response from direct-coupled (dc) up to 500kHz. The MTI-2100's modular design has the flexibility to be tailored to specific requirements through the use of a wide range of interchangeable and custom fiber-optic probes. These probes are immune to electromagnetic interference (EMI) and operate on almost any type of surface: metallic, composite, plastic, glass, ceramic or liquid.


  • Modal Analysis
  • Ultrasonic Horn Vibration Displacement
  • Position Sensing
  • Fatigue Testing
  • Surface Flaw Detection
  • Edge Detection
  • Piezo Motion
  • Bearing Analysis
  • Vibration Measurements


  • Dual-channel capability permits simultaneous measurements of amplitude and phase
  • Selectable metric or English units
  • Reflective compensated units available to automatically adjust to target reflectivity changes
  • Digital display readout in engineering units eliminates the need to convert volts to displacement
  • Out-of-range indicator notifies the user if the target moves out of the linear range
  • Interchangeable probe modules allow the user to select from seven standard fiber-optic probe designs, providing 14 different standard measurement ranges and resolutions
  • High-resolution module resolves to 0.1 µin. standard or 0.01 µin. (2.5A°) optional. With external filtering, 0.004-µin. (0.1nm) resolution is possible
  • Standard 0-to-10 VDCanalog real-time output is compatible with most signal conditioning equipment
  • RS-232 output for computer interfacing
