Claim:
1. A probe for optical imaging which guides light entering a tip side to a rear side, the probe comprising: a non-rotatably disposed fixed side optical fiber incorporated in a substantially tube-shaped catheter; a first optical path conversion means disposed on a tip side of the fixed side optical fiber and driven by a first motor to rotate, thereby emitting a light ray in a substantially radial direction; a rotation side optical fiber positioned between the fixed side optical fiber and the first optical path conversion means, optically connected by an optical rotary connector, and driven by a second motor to rotate; and a second optical path conversion means for rotating and emitting light by inclining an optical path to a tip side of the rotation side optical fiber by a minute angle with respect to a rotation center, wherein the fixed side optical fiber, the first optical path conversion means, the rotation side optical fiber, and the second optical path conversion means are collinearly disposed.
