Abstract: Improved fiber optic remote sensor An optically driven, electromagnetically oscilla- ting resonant sensor subjected to a stress force wherein the optical driving energy and the opti- cally communicated signal generated in response to the stress force are both communicated a substan- tial distance along a single optical fiber. A portion of the supply energy drives the oscillatory mechanism and a portion is reflected to a frequency detector by the shuttering action of the resonant element. The device may be configured so as to be electrically driven and optically sensed, optically driven and electrically sensed, or both optically driven and optically sensed for maximum retrofit versatility in past, present, and future process control systems.
