Rayleigh Fiber Optics Gyroscope - IEEE Photonics Technology Letters
A novel kind of fiber-optic gyroscope based on Rayleigh backscattering in a fiber-ring resonator is presented in this letter. The information on the rotation rate is obtained from the composed response of the fiber ring to an optical time-domain reflectometry (OTDR) instrument. The developed model based on the coherence properties of the Rayleigh scattering yields to a polarization-insensitive ...
متن کاملFiber Optic Gyroscope
This paper describes the development of Fiber Optic Gyroscope (FOG) for Space applications at LEOS. The sensor has all solid-state optical devices for the precise measurements of mechanical rotation. The basic phenomenon underlying optical rotation sensing is known as the Sagnac effect. In the Sagnac effect two identical light beams traveling in opposite directions around a closed loop path exp...
متن کاملExperimental Evaluation of a Fiber Optics Gyroscope for Improving Dead-Reckoning Accuracy in Mobile Robots
This paper presents results from the experimental evaluation of a state-of-the-art fiber-optics gyroscope. The purpose of our experiments was to evaluate the suitability of this gyroscope for enhancing dead-reckoning in mobile robots. The evaluated gyroscope was the “Autogyro Navigator” made by Andrews. For a 4×4 m square path the dead-reckoning error when using this gyro was less than ±1.2° in...
متن کاملMode-locked fiber laser gyroscope.
We propose and demonstrate a novel fiber-optic gyroscope in the form of a mode-locked laser consisting of a laser cavity formed by a planar mirror at one end, a gain medium, and a Sagnac interferometer at the other end. The Sagnac interferometer serves as a reflector as well as a rotation-sensing element. The output of the gyroscope is a series of short optical pulses. The separation of two set...
