Abstract
An optical fiber scanning probe includes a rotor and at least one optical fiber. The rotor includes a torque rope rotatable about its central axis. The optical fiber is disposed on the rotor and eccentric relative to the torque rope. A central axis of the optical fiber is substantially parallel to the central axis of the torque rope. When the torque rope rotates about its central axis, the rotor brings a free end of the optical fiber to scan along an arc path.
