    摘要: It is intended to provide an internal defect inspection method and an apparatus for implementing the method by which an ultrasonic wave is excited in a sample without contact with the sample and accordingly without damaging the sample, and an ultrasonic wave from any internal defect of the sample is detected without being affected by the sample surface, in a non-contact state and with high sensitivity.By the internal defect inspection method, an ultrasonic wave is emitted from an ultrasonic wave transmitter toward a sample, an ultrasonic wave reflected by the sample is detected as an interference signal with an imaging type common-path interferometer, an ultrasonic wave signal is obtained from the interference signal, and any defect within the sample is detected from the ultrasonic wave signal.
