| Outline of Final Research Achievements |
Fiber-optic sensing of stress direction was attempted using dye-doped polymer optical fiber. The former fiber-optic strain sensors do not have this function. The sensing mechanism is as follows. 1) Molecular orientation of dye was induced by the stress applied to the fiber. 2) Linearly polarized light was coupled to the fiber. 3) Output light intensity changes depending how well the polarization plane matches the molecular orientation.
As a result, changes in output intensity as a function of stress direction was observed using the fabricated fiber and proposed measurement system.
