PROBLEM TO BE SOLVED: To simplify an operation for adjusting a polarization state.SOLUTION: The optical image measurement device is configured to comprise: dividing light from a light source into signal light and reference light; generating interference light of the signal light and the reference light via a measured object; and forming an image of the measured object on the basis of a detection result of the interference light. The optical image measurement device includes: a first optical fiber that guides the signal light via the measured object; a second optical fiber that guides the reference light; and a polarization controller. The polarization controller holds a part of one or both of the first optical fiber and the second optical fiber in a curved shape, and by changing the curved shape, the polarization state of the light to be guided to the optical fiber is changed. |
