Abstract

An OCT imaging apparatus includes a diffraction grating 141 that divides an incident light for each wavelength, a line sensor 139 that receives the divided light and converts it into an electric signal, a motor-driven stage 210 that adjusts a relative position between a light-receiving surface of the line sensor 139 and the light, and a display control unit 125 that displays a spectrum of the light which a sensor receives corresponding to adjustment, wherein an interference light of a measurement light and a reference light is properly aligned relative to the sensor.
