Claim:
1. An optical imaging probe for guiding rearward a light entering a front end, comprising: a rotation driving source having a rotor arranged in a substantially cylindrical shape and a substantially cylindrical coil having an inner circumference configured to cover a peripheral of the rotor, the rotation driving source being adapted to drive and rotate the rotor; a first single-mode optical fiber inserted and fixed over an axial direction in a rotation center side of the rotor, a front end of which a light is able to enter; a second single-mode optical fiber supported at a 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, wherein the optical path correcting means is adapted to expand and collimate a light transmitted from one of the first and second single-mode optical fibers and pass the light through the gap, and then guide the light to the other one of the first and second single-mode optical fibers, wherein the optical imaging probe further includes a tubular rotation shaft fixed in an axial direction in a rotation center side of the rotor and supported in a rotatable manner, wherein an end face of the first single-mode optical fiber is inserted within the tubular rotation shaft with an end of the first single-mode optical fiber forming a substantially flat plane with an end of the tubular rotation shaft.
