A method of calibrating an optical frequency of light emitted from a wavelength-swept light source thereby allowing it to compensate for an error of a wavelength includes performing a first process of measuring an optical frequency range of the emitted light while changing a control parameter associated with an optical frequency sweeping mechanism and determining a correspondence between the control parameter and the optical frequency range, performing a second process of measuring a maximum of a gain of an active medium included in the wavelength-swept light source and determining a correspondence between the maximum of the gain and the control parameter, performing a third process of determining a relationship between the optical frequency range of the emitted light and the control parameter corresponding to the maximum gain of the active medium, and performing a fourth process of adjusting the control parameter based on the determined relationship. |
