Abstract
A beam distributor apparatus employing an eccentrically mounted retroreflector prism is driven to revolve about a central axis by a motor/encoder to direct an input beam to a plurality of optical fibers in sequence. The retroreflector prism possesses the property of reflecting a beam in a directional parallel to the incident beam but displaced laterally therefrom. In one arrangement, a synchronously triggered laser is used as the light source. In a second embodiment, a non-laser light source is employed with a shutter coupled to be triggered in synchronism with the position of the rotating prism relative to the output optical fibers.
