Paper Abstract

The paper describes three examples of low-cost, low-power signal processing techniques used in building prototypes of low/medium performance Fiber Optic Gyroscopes. The prototypes were developed at the Mercer Engineering Research Center, in an ongoing U.S. Air Force funded effort to develop a Fiber Optic Gyroscope replacement for existing mechanical rate gyroscopes used in a wide variety of applications. The novelty of applied methods consists of a very small number of elements used, and a very low power consumed by the signal processing electronics. The noise suppression was achieved due to small number of elements, synchronous homodyne detection scheme, and resonance amplifier/filter techniques. The Sagnac interferometric optics with 50/50 splitter/combiner, and 2 X 2 directional coupler, and optical phase shifter at 820 nm and 1500 nm wavelengths have been developed as a part of this ongoing effort and were used in the experiments.
