    • The present invention relates to an optical fiber characteristic distribution sensor comprising a structure to effectively reduce the measurement errors of position in the temperature distribution measurement etc. The sensor comprises an optical fiber section, part of which is installed in an object to be measured and to which probe light and pumping light are inputted in opposite directions. The optical fiber section includes a marker portion where data relating to the shape of a BGS in the maker has been preliminarily measured in a state where the optical fiber section is installed in a normal state. At the time of calculating the characteristic distribution in the longitudinal direction of the optical fiber section while measuring the data relating to the BGS shape, the errors of the calculated gain occurrence position are corrected, for example, by shifting the scanning range of phase difference between the probe light and the pumping light. The amount of shift of the scanning range of phase difference is given based on a difference value between the phase difference at the time of measurement when the BGS that reflects the gain that has occurred in the marker portion is measured, and the reference phase difference when data relating to the already known shape of the BGS in the marker portion has been preliminarily measured.

    • The present invention relates to an optical fiber distribution type detecting method and the like equipped with a structure for enabling efficient measurement of a temperature distribution or strain distribution. This method regulates a modulation frequency and modulation index for probe light and pumping light opposingly incident on an object from a light source and a phase difference between the probe light and pumping light, thereby successively setting the length and location of search domains in a region to be measured. In particular, a detection process is executed while resetting the search domain length shorter at a predetermined interval of time or when an abnormality is detected. Thus partly changing the distance resolution for a specific region in the course of the detection process enables efficient measurement operations in a short time.
