摘要： PROBLEM TO BE SOLVED: To detect nondestructively a pearl internal structure using a photoelectric conversion, based on optical interference principle, signal collection, and scanning technique. SOLUTION: A method of inspecting an internal structure of accessories, such as pearls and precious stones, etc. comprises: a step of projecting a light on an arm for a reference which can reflect the light by carrying out spectroscopy of the light generated from a low-coherence optical source with a spectrometer to the first beam and the second beam, and for the first beam and the second beam, changing a sample arm for fixing a measured article and the optical distance, respectively; a step of regulating the optical distance so that an interference signal is generated, by making the reflected light from the arm for the reference interfere with the reflecting light from the measured article of the sample arm; a signal replacing step involving acquiring of a strong signal of one-dimensional reflecting light in the depth direction of the measured article, by converting the interference signal into an electrical signal and transferring the electrical signal to a signal analyzer while changing the optical distance and the arm for the reference; and a scanning step of acquiring an optical fault image which shows a two-dimensional internal structure of the measured article, by performing scanning on the measured article.
