Abstract
An optical slip ring assembly couples an optic signal from a rotating source to a stationary detector. The rotor of the optical slip ring comprises rotor optic fibers each having a first end coupled with the optic signal source and a second light-emitting end which is aimed at the stator optic fibers. The stator optic fibers each have a first pickup end mounted in the stator block and are positioned in a radially symmetric array surrounding the rotor. An optic signal transmitted from the source through the rotor fiber is picked up by the stator fibers.
