Summary
A new plastic optical fiber (POF) force sensor uses surface plasmon resonance (SPR) to detect force-induced deformations. This novel optical fiber sensor achieves a resolution of 22 mN with a linear response up to 0.5 N.
Area of Science:
- Optoelectronics
- Fiber Optic Sensors
- Plasmonics
Background:
- Surface Plasmon Resonance (SPR) is a label-free optical sensing technique.
- Plastic Optical Fibers (POF) offer advantages in cost and flexibility over silica fibers.
- Integrating SPR with POF can lead to novel sensor applications.
Purpose of the Study:
- To design and develop a novel force optical fiber sensor.
- To investigate the use of SPR in a D-shaped POF for force sensing.
- To experimentally validate the performance of the proposed force sensor.
Main Methods:
- A force sensor system was designed using a plastic optical fiber (POF) patch and an SPR sensor in a D-shaped POF.
- Applied force caused deformation in the POF patch, altering light mode profiles.
- Changes in SPR spectra were monitored using a spectrometer and light source.
Main Results:
- The force sensor demonstrated a resolution of approximately 22 mN.
- An excellent linear response was observed in the force range of 0 N to 0.5 N.
- The SPR spectra shifted in response to applied force variations.
Conclusions:
- The developed POF-based SPR sensor is effective for force detection.
- The sensor exhibits high sensitivity and linearity within the tested range.
- This approach offers a promising method for optical force sensing applications.
