Title STRESS SENSOR meetings
Abstract This stress sensor comprises: a light source which emits light of a first wavelength and light of a second wavelength that is different from the first wavelength; and an optical waveguide on which the light of the first wavelength and the light of the second wavelength is incident. The optical waveguide is provided with: a core in which a fluorescent dye is dispersed; and a cladding which covers the circumference of the core. The fluorescent dye is excited by the light of the first wavelength and emits light of a third wavelength; and the second wavelength and the third wavelength are in the visible light range.

In order to cover the side of the aforementioned optical waveguide, the dispersion characteristic component which is stuck to the inspection object and, possessing,
The aforementioned optical waveguide, covers around the core, and the aforementioned core which make the fluorescence dye disperse, the clad, having,
As for the aforementioned fluorescence dye, being excited in light of the aforementioned 1st wave length, light of the 3rd wave length which is the visible optical limits the stress sensor which radiates.
[claim3]
3. In order to cover the side of the aforementioned optical waveguide, in the claim 1 which possesses the dispersion characteristic component which is stuck to the inspection object the stress sensor of statement.
[claim4]
4. Possessing plural aforementioned dispersion characteristic components,
As for the aforementioned dispersion characteristic component of husband , in order to cover the plural places of the side of the aforementioned optical waveguide, in the claim 3 which is stuck to the inspection object the stress sensor of statement.
[claim5]
5. The inspection object is the cylinder,
