ABSTRACT:
An optical coherence tomography device includes: a light source16; a light splitting section19that splits light source light into reference light19and measuring light28with which a sample22is irradiated; an interfering section19that allows the measuring light28to interfere with the reference light29to generate interference light; a photodetectiong section26that measures interference light; a movable measuring head201that changes the irradiating position and/or direction, irradiated with the measuring light28, by a motion of the measuring head20; a mechanical quantity sensor38that measures the motion of the measuring head201; and an operating section27that obtains information on the sample22, based on the interference light measured by a photodetectiong section26and the motion of the measuring head201measured by the mechanical quantity sensor38. Thus, an optical coherence tomography device capable of capturing an image at a high speed with a simple structure can be provided.
