This study introduces a low-cost fiber Bragg grating sensor system using code-division multiple access for signal separation. The system demonstrates fast response speeds and minimal signal cross-talk, suitable for various strain measurements.

Area of Science:

  • Optoelectronics
  • Fiber optic sensing technology
  • Signal processing

Background:

  • Fiber Bragg grating (FBG) sensors are widely used for measuring physical parameters.
  • Multiplexing FBG sensors in a single optical fiber is challenging due to signal overlap.
  • Existing methods for FBG sensor multiplexing can be complex or costly.

Purpose of the Study:

  • To propose and experimentally validate a novel multiplexing scheme for FBG sensors.
  • To utilize code-division multiple access (CDMA) for efficient sensor signal discrimination.
  • To develop a low-cost, high-speed FBG sensor system.

Main Methods:

  • Implementation of a multiple FBG sensor system.
  • Employment of a light-emitting diode (LED) as the light source.
