Introduction

Fiber Optics Sensors (FOS) are high performance sensors and in some fields have overwhelming and proven advantages over other technologies.

Typical Configuration

  1. Transmission mode
  2. Reflection mode

Modification Method

  • Gratings
    • Fiber Bragg Grating (FBG)
    • Long Period Grating (LPG)
  • SMS (Cascade of optical fibers: Single-mode Multi-mode Single-mode)
