<P>PROBLEM TO BE SOLVED: To provide an optical sensor measuring apparatus which can eliminate a high-speed data processor and can be downsized. Ž<P>SOLUTION: The optical sensor measuring apparatus includes: an arithmetic circuit 41 for, on the basis of data in which reflection spectra obtained from a plurality of FBG sensors 31, 32, 3n, respectively, exceed a threshold, determining the center of each reflection spectrum; a threshold storage register array 43 for storing optimum thresholds for determining the center of the reflection spectra from the FBG sensors 31, 32, 3n, respectively; and a comparator circuit 44 for outputting an optimum threshold in accordance with each reflection spectrum to the arithmetic circuit 41 by comparing the data on the reflection spectra obtained from the FBG sensors 31, 32, 3n, respectively, with the optimum thresholds stored in the threshold storage register array 43. A threshold necessary for calculating the center of the reflection spectra reflected from the FBG sensors 31, 32, 3n, respectively, by the arithmetic circuit 41 is selected from the optimum thresholds stored in the threshold storage register array 43 in advance.
