ABSTRACT:
An optical slip ring for acting as an interface between rotary member and a stationary detector includes a source for generating a light beam directed at a sensor on the rotary member and an optical fiber transmitting said beam to the sensor. The sensor generates in response a sensor signal indicative of a physical parameter of interest. This sensor signal is transmitted through the fiber to an output lens for pick up by a stationary detector.
