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 fundament...
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 کاملLarge-area fiber-optic gyroscope on a multiplexed fiber network.
We describe a fiber-optic gyroscope based on the Sagnac effect, realized on a multiplexed telecom fiber network. Our loop encloses an area of 20 km² and coexists with Internet data traffic. This Sagnac interferometer is capable of detecting signals that are larger than 10(-8) (rad/s)/√Hz, thus approaching ring laser gyroscopes without using a narrow-linewidth laser or sophisticated optics. The ...
متن کاملInvestigation on Closed-loop Fiber Optic Gyroscope Structure and Operation
In this paper, I reviewed comprehensively the structure and operation of closed-loop IFOGs, Feedback Erbium-doped fiber amplifier (EFDA) FOGs, called FE-FOG. The procedure of finding the Sagnac shift for closed-loop IFOG has been studied. The signal processing in the closed-loop IFOG was simulated using PSCAD software. In the closed-loop IFOG, the phase shift was derived through frequent use of...
متن کاملPhase-reading, all-fiber-optic gyroscope.
An open-loop, all-fiber-optic gyroscope with wide dynamic range and linear scale factor is described. This novel approach converts the Sagnac phase shift into a phase shift in a low-frequency electronic signal by using optical phase modulation followed by amplitude modulation verify the theoretical predictions.
