ABSTRACT:
A single channel optical slip ring assembly comprising first and second optic fibers, a first lens optically coupled to one end of the first optic fiber for collimating a light signal into a parallel light beam having a selected diameter substantially larger than the first and second optic fiber, a second lens optically coupled to one end of the second optic fiber for focusing a collimated light beam having the selected larger diameter into the second fiber end, and means for rotatably mounting the first lens to the second lens so that the lenses are axially aligned along the axis of rotation and are separated by a selected gap for axially transmitting a collimated light signal therebetween whereby the first and second fibers are optically coupled during relative rotation.
