Abstract: The present disclosure relates to a method of correcting a three-dimensional image. To correct an image distorted by coherence gate curvature (CGC) occurring by an optical system, the method generates a three-dimensional image of a sample holder on which an object to be measured is placed from an interference signal, generates a CGC profile on the basis of an image of a cover glass of the sample holder appearing in the three-dimensional image, generates a CGC fitting curve from the CGC profile, and corrects the interference signal by using the CGC fitting curve. The present disclosure also relates to an OCT system capable of performing a method of correcting a three-dimensional image.
