ABSTRACT:
A method is disclosed wherein a portion of a sensor part of an optical fiber sensor is embedded in an adhesive between two joined members, and peeling in an adhesive joint of the two members is detected on the basis of measuring optical characteristics from the optical fiber sensor when the optical fiber sensor is irradiated with light from a light source while one member is vibrated by vibration means. The method comprises the steps of determining the temperature of the two members during measurement on the basis of the optical characteristics from the sensor part exposed outside of the adhesive; determining, on the basis of the temperature determined during the measurement, the measurement range in which the optical characteristics from the optical fiber sensor are measured; and measuring the variation in the optical characteristics from the optical fiber sensor within the determined measurement range while the member is being vibrated by the vibration means.
