An optical coherence tomography device includes: a light source 16; a light splitting section 19 that splits light source light into reference light 19 and measuring light 28 with which a sample 22 is irradiated; an interfering section 19 that allows the measuring light 28 to interfere with the reference light 29 to generate interference light; a photodetectiong section 26 that measures interference light; a movable measuring head 201 that changes the irradiating position and/or direction, irradiated with the measuring light 28, by a motion of the measuring head 20; a mechanical quantity sensor 38 that measures the motion of the measuring head 201; and an operating section 27 that obtains information on the sample 22, based on the interference light measured by a photodetectiong section 26 and the motion of the measuring head 201 measured by the mechanical quantity sensor 38. Thus, an optical coherence tomography device capable of capturing an image at a high speed with a simple structure can be provided.
