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.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber underlying method capable efficiently underlaying optical fibers in a tunnel in a short time. SOLUTION: At the time of underlaying optical fibers in a tunnel 1, a plurality of grooves are formed in the inner wall surfaces 2 of the tunnel 1 at predetermined intervals in the direction which intersects the direction of the axis of the tunnel 1, and signal cables 6 comprised of optical fibers and protective tubes are arranged in the grooves and fastened by an adhesive. The signal cables 6 are further fixed to the wall surfaces 2 by gage-length fixing bolts at regular intervals and fixed by protective tube fixing bolts 9 at the midpoints of the signal cables 6. In the signal cables 6, optical fibers are inserted into protective tubes made of a relatively hard synthetic resin, and the optical fibers and protective tubes are previously fixed together at every regular measurement intervals to provide a degree of initial distortion for the optical fibers. By using the signal cables 6, there is no need for providing initial distortion for optical fibers at the time of underlaying cables, and it is possible to perform efficient underlaying work.

摘要： PROBLEM TO BE SOLVED: To build a method for quickly installing an optical fiber by setting a bendable pipe along a surface of a structure, inserting the optical fiber inside the pipe and uniting the optical fiber and the pipe. SOLUTION: A pipe 2 is arranged while curved to trace an inner surface of a tunnel 1. The pipe 2 is bendable and can be arranged to trace the surface while being freely bent even if the surface of the structure is not flat. After the pipe 2 is arranged by a desired length, an optical fiber 3 is inserted in the pipe 2. As a method for inserting the optical fiber 3, for example, an air flow is sent by blowing the air into the pipe 2 and the optical fiber 3 is inserted in the pipe 2 by this air flow. Although it is necessary to unite the optical fiber 3 and the pipe 2 after the optical fiber is inserted to the pipe 2, a method used for the uniting is, e.g. forming the pipe 2 of a thermally shrinkable synthetic resin, applying heat by pouring hot water to the pipe 2 after inserting the optical fiber or by the like manner and, thermally shrinking the pipe.
