Abstract
Provided is optical imaging probe that is able to obtain stable observation image by optical path correction. It includes a rotation driving source adapted to drive and rotate a rotor; a first single-mode optical fiber inserted and fixed over the axial direction in the rotation center side of the rotor, the front end of which light is able to enter; a second single-mode optical fiber supported at the rear end side of the first single-mode optical fiber in a non-rotatable manner; and a gap and optical path correcting means interposed between the first single-mode optical fiber and the second single-mode optical fiber, and the optical path correcting means is adapted to expand and collimate the light transmitted from one single-mode optical fiber and pass it through the gap, and then guide it to the other single-mode optical fiber.
