Patent ID: 7549337

Claim:
A peeling inspection method wherein at least one member selected from at least two members joined using an adhesive is provided with vibration means, a portion of a sensor part of an optical fiber sensor is embedded in the adhesive for joining the two members, and peeling in an adhesive joint of the two or more members is detected on the basis of optical characteristics from the optical fiber sensor when the optical fiber sensor is irradiated with light from a light source while the member is vibrated by the vibration means, the method comprising the steps of: determining a temperature of the two members during measurement on the basis of the optical characteristics from that portion of the sensor part which is exposed outside of the adhesive; determining, based on the temperature determined during the measurement, a measurement range in which the optical characteristics from the optical fiber sensor are measured; vibrating the member by means of the vibration means; 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.
