Abstract
Optical slip ring apparatus is disclosed in which radial light signals formed in a continuous ring are transmitted between a barrel and a surrounding sleeve within which the barrel is rotatably mounted. The ring of light signals is produced and detected respectively by a plurality of light emitting diodes and light detector means carried on the barrel and the sleeve. The light detector means may include an optical fiber bundle for transmitting light signals to a remote detector. In one embodiment, a plurality of optical and electromechanical slip ring channels are incorporated into a single device.
