Abstract
The present invention is a limited rotation Fiber Optic Rotary Joint (FORJ) of one or more optical channels. This will enable one or more optical signals to pass across a rotational interface for a fixed number of rotations. For many applications, such as a winch or certain robotic joints, an unlimited number of rotations in either direction is unnecessary. For these types of applications a limited rotation FORJ is an attractive option because they typically have lower loss, are less complex, and have higher reliability.
