Abstract

A design for a Fiber Optic Rotary Position Transducer (FORM') has been developed, and major components tested, at Teledyne Ryan Electronics in San Diego, California. This rotary position transducer exhibits a full angular span of 90 (±45) degrees with an angular resolution of approximately 0.09 degrees (10 bits). The physical dimensions are approximately two inches outside diameter with a thickness of about one inch. The transducer is designed to meet standard military specifications. Its optical telemetry system operates on the principle of Time Division Multiplexing (TDM). An optical signal processor consisting of an optical transmitter and receiver communicates via a single optical fiber to the transducer. A digitally encoded reflective disc coupled mechanically to a shaft and optically to a fiber optic read head constitutes the actual transduction mechanism.
