摘要： PROBLEM TO BE SOLVED: To provide a method for specifying corroded parts of structures and capable of highly precisely specifying corroded parts of structures and specifying factors of the occurrence of transmission losses of optical fibers. SOLUTION: Beams of light two wavelengths, a beam of light with a wavelength λb having a large transmission loss due to gaseous hydrogen and a light of a wavelength λa having a smaller transmission loss than that of the light of the wavelength λb having a large transmission loss due to gaseous hydrogen, enter an optical fiber as beams of light with wavelengths for detecting gaseous hydrogen. Transmission losses of the beams of light in the longitudinal direction of the optical fiber are each determined. Transmission losses of the beams of light of the two wavelengths in a prescribed section are compared with each other on the basis of the determined transmission losses. It is distinguished and determined whether transmission losses which have occurred in the optical fiber are absorption losses due to hydrogen or losses due to bending to detect the presence or absence of occurrence of gaseous hydrogen in the prescribed section and specify parts at which gaseous hydrogen has occurred in a long structure 81 in this method.

摘要： PROBLEM TO BE SOLVED: To provide an m-time diffusion filter capable of enlarging a diffusion time width without increasing computational quantity, and to provide a diffusion transmission system using the m-time diffusion filter.
SOLUTION: In the impulse response of a reference diffusion filter, when the finite time section is extended to m=3 times, the impulse response of a 3-time diffusion filter is achieved. A symbol cycle Ts is not changed. In a diffusion symbol p
k outputted by the impulse response of the 3-time diffusion filter, the diffusion symbol p
k of a symbol timing in k=3n not corresponding to k=3n to be the moving destination of the diffusion symbol s
n when the impulse response of the reference diffusion filter is extended to 3 times is defined as 0. Thus, the diffusion time width is enlarged to m times compared to the reference diffusion filter. However, since only the diffusion symbols whose amplitude becomes zero increase, the computational quantity is not changed from the case of the reference diffusion filter.

摘要： PROBLEM TO BE SOLVED: To prevent a variable wavelength type optical filter from having a break of an intermediate wavelength. SOLUTION: The variable wavelength optical filter has a band-pass filter main body 14 with a reflecting film 10 and a spacer layer 12, and a substrate 16. The reflecting film 10 is formed by laminating alternate dielectric layers differing in refractive index. The spacer layer 12 is sandwiched between a couple of reflecting films 10 at its front and rear parts and has tapered slope surfaces as its top and reverse surface so that the thickness continuously varies. The filter main body 13 varies in value of transmission wavelength λ as the thickness of the spacer layer 12 varies. To vary the transmission wavelength, the band-pass optical filter main body 13 is moved so that the position of incidence of incident light L in on the band-pass optical filter main body 14 changes to (1), (2), (3), and (4) in order.
