Overview and Improving Fiber Optic Gyroscope Based on MEMS/NEMS Fabrication

The measurement of the rotation of rigid solids is of considerable interest in a number of areas. Rotation detectors are not only used in aircraft, missiles etc. military fields have also been developed for new civil fields such as automobile navigation, antenna stabilization, crane control, unmanned vehicle control, wind and renewable energy platform stabilization. In this paper, the fundamental operations of fiber-optic gyroscopes are reviewed. Performance-limiting phenomena are discussed along with methods to reduce their effect on the rotation-rate signal. Current technology and performance of new demodulate systems are presented applicable to MEMS technology. The FOG with scanning phase-shift demodulates technology based on anti-noise filter circuit improvement of DSP algorithm is proposed in this paper. New methods, which are used to fabricate the nanometer optical fiber, are discussed.
