摘要： In an optical non-destructive inspection method and an optical non-destructive inspection apparatus which can perform inspection accurately in a short time, a measurement object is heated with a laser beam without destroying the measurement object, and a state of the measurement object is determined based on a curve shape of a temperature rise characteristic of the measurement object. In the method and the apparatus, a heating laser beam source (21), at least one infrared detector (31, 32), a control unit (50), and a storage unit (60) are used. The storage unit (60) stores a parameter state-time constant characteristic in which a parameter corresponding to a state of the measurement object is correlated with a time constant indicating the curve shape of the temperature rise characteristic that varies depending on the state of the parameter. The control unit (50) determines the time constant based on the curve shape of the temperature rise characteristic, which extends from a heating start time point to a time point at which a saturated temperature is reached, and determines the state of the parameter of the measurement object based on the determined time constant and the parameter state-time constant characteristic.
