Probe for optical imaging

A probe for optical imaging which guides light entering a tip side to a rear side, the probe comprising:

• a fixed side optical fiber non-rotatably disposed and 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 and rotated by a first motor to rotate and emit a light ray forward at an angle inclined with respect to a rotation center;
• a rotation side optical fiber disposed between the fixed side optical fiber and the first optical path conversion means, optically connected by an optical rotary connector, and driven and rotated by a second motor;
• and
• a second optical path conversion means for rotating and emitting light to a tip side of the rotation side optical fiber by tilting an optical path by a minute angle with respect to a rotation center, and emitting a light ray toward the first optical path means,
• 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 substantially collinearly disposed,
• wherein the light ray is emitted forward by penetrating the optical rotary connector, the second optical path conversion means, and the first optical path conversion means in order from the fixed side optical fiber.
