Abstract
A fiber optic rotary joint includes a first fiber optic cable operably coupled to one of a stator and a rotor and a second fiber optic cable operably coupled to the other of the stator and the rotor. The stator and the rotor define a free space optical path between the first fiber optic cable and the second fiber optic cable. The rotor is rotatable about an axis of rotation parallel and collinear with an optical axis of at least one end of the fiber optic rotary joint. A first beam conditioning mechanism is configured to condition a light beam emitted from the first fiber optic cable and a second beam conditioning mechanism is configured to focus the conditioned light beam into the second fiber optic cable.
