摘要： PROBLEM TO BE SOLVED: To monitor large deformation of invisible location in a large-scale structure.
SOLUTION: An optical fiber sensor exemplified in BOTDR is used. A quartz optical fiber having small attenuation of signal for long distance is used. The quartz optical fiber is apt to break, by large extension and distortion. So, by placing it in a state with the marginal length given at an arbitrary location by winding as a wave, a break cannot easily occur for monitoring objective large distortion. By arranging the optical fiber in grid on a plane structure, the location causing deformation of the structure can be detected.

摘要： PROBLEM TO BE SOLVED: To provide an optical gas sensor capable of detecting gas with high sensitivity by compensating for low reaction characteristics and capable of arranging a measuring environment by excepting a substance lowering sensitivity.
SOLUTION: The film thickness of a coating material is calculated from the measured light path difference between the light reflected from the interface of the coating material 1 at the leading end of a light transmission medium 2 and air, and the light reflected from the interface of the coating material 1 and the light transmission medium 2 to calculate the concentration of the gas determined by the film thickness. An interference system 5 is used in a light detecting part in order to measure the light path difference. Further, separately from the interference system for measuring the light path difference, light with a wavelength for exciting a substance lowering the function of the coating material 1 is allowed to irradiate. Furthermore, by mixing Ag with Pd as the coating material 1, a change in the occulusion quantity of the gas with respect to the concentration of the gas is reduced.
