ABSTRACT:
Binary information developed on a rotating member is applied in the form of light signals to one end of an optical fiber which is disposed about the rotating member and positioned adjacent a stationary light detector. The surface of the optical fiber is roughened so that a portion of the light that axially propagates along the optical fiber is transmitted through the roughened wall of the fiber and is received at the light detector. The latter converts the thus received light signals into corresponding binary signals. In accordance with one aspect of the present invention, plural independent data coupling channels may be employed.
