PROBLEM TO BE SOLVED: To provide an optical tomographic image acquisition apparatus capable of acquiring accurate optical tomographic images.SOLUTION: An optical probe 40 comprises an optical fiber 41, a GRIN lens 42, a protective material 43, and a sheath 44. A second end 41b of the optical fiber 41, the GRIN lens 42, and the protective material 43 are configured to form a probe movable section 40A with relative positions thereof fixed. The probe movable section 40A is provided with a gap between itself and an inner peripheral surface of the sheath 44, and is configured to be rotatable inside the sheath 44. An optical tomographic image reference position to be used as a reference when acquiring an optical tomographic image is determined based on an image position on one of interfaces in the probe movable section 40A in the optical tomographic image.SELECTED DRAWING: Figure 2 |
