ABSTRACT:
Optical slip rings which permit signals to be transferred from a rotating dy to a non-rotating body without any physical contact. Fiber optic bundles are utilized to conduct light signals on one body to separate fiber optic bundles on the other body. Light is projected across a small gap from the rotating bundle to the non-rotating bundle. Other variations use multiple channels, wave guides, derotating prisms and concentric annular mirrors to achieve signal transfer. The optical slip rings can transfer any signal which may be converted to a light signal.
