Abstract
An optical slip ring provides optical communication between a pair of members free to rotate with respect to each other. These members may be a pair of optical fibers, an electrical conductor and an optical fiber or a pair of electrical conductors. One member is attached to a first mounting device and the other member is attached to a second mounting device. One optical receiver is positioned in the center of the first mounting device on a common axis of rotation with respect to the second mounting device. The other optical receiver is mounted on the second mounting device, positioned on the common axis of rotation. One optical emitter is mounted off center on the first mounting device and the other optical emitter is mounted off center on the second mounting device. The optical emitter mounted on the first mounting device is aimed at the optical receiver mounted on the second mounting device, and the optical emitter mounted on the second mounting device is aimed at the optical receiver mounted on the first optical device. Relative rotation between the members does not change the optical communication between the optical emitters and their respective optical receivers.
