<p>In the present invention, by way of a single optical fiber that is wound and attached to the outer circumference of a cylindrical body and that senses temperature and strain in the cylindrical body deformed by the pressure of a liquid, the pressure of the liquid is found from the strain in the cylindrical body generated by the pressure of the liquid by detecting changes both in the Brillouin scattering frequency and in the Rayleigh scattering frequency for the light scattered in the optical fiber and thereby separating and simultaneously detecting the temperature and strain in the cylindrical body.</p> |
