High-precision Distributed Optical Fiber Sensing Monitoring System

Model:OSI-S

Description

The OSI-S is a high-precision distributed optical fiber sensing monitoring system. Its principle is based on optical frequency domain reflection (OFDR) technology. Strain and temperature can be captured with mm spatial resolution over the entire sensing fiber. The system is designed to be suitable for various types of sensors, such as conventional single-mode fiber and weak reflective FBG array. Its measurement accuracy is ±0.1℃ or ±1.0με. The OSI-S can simultaneously measure tens of thousands of sensing points along a single fiber. It is an excellent tool for high resolution and accuracy sensing applications.

Feature

  • Ultra-high measurement accuracy and spatial resolution

  • Excellent stability by self-calibration without user intervention

  • Shape sensing can be used for deformation measuring

  • Single-mode fiber and weak reflective FBG array are both available

  • The customized service is supported, such as dynamic demodulation and multi-channel upgrades

  • Lead length can be adjusted between zero and 1km by customization for remote measurement

Applications

  • Structural health monitoring

  • Composite material fatigue testing

  • Strain and temperature testing for automobile structure

  • Strain and temperature field reconstruction for other areas
