EINRICHTUNG ZUR UEBERTRAGUNG VON INFORMATIONEN ZWISCHEN ZWEI ZUEINANDER BEWEGLICHEN TEILEN

摘要

There is provided optical arrangements rather than conventional electrical slip rings for transferring control information between two members, one of which is rotatable relative to the other. The information may be transferred by a laser beam which is pulse modulated. The use of an optical method overcomes the disadvantages associated with electrical slip rings, for example, poor contact, unreliability, electromagnetic interference and mechanical complexity.
