PROBLEM TO BE SOLVED: To provide an optical tomographic imaging device capable of keeping a polarization state without moving a measurement light source by simplifying a drive mechanism, and capable of suppressing loss or an aberration of light.SOLUTION: An optical tomographic imaging device acquires a tomographic image of an examined object on the basis of light obtained by wave-combining return light from the examined object irradiated with measurement light through a scanning part and reference light corresponding to the measurement light. The optical tomographic imaging device has: a division part dividing light emitted from the light source into the measurement light and the reference light; and a focusing part disposed between the division part and the scanning part in an optical path of the measurement light. The optical tomographic imaging device makes optical path branch means through which the measurement light is transmitted when radiating the measurement light onto an examined eye leave from the optical path. |
