Investigation 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 کاملFpga-based Hardware Design of Closed Loop Control for Fiber Optic Gyroscope
The stability, reliability and miniaturization of fiber optic gyroscope (FOG) are always the research focuses and difficulties. This paper presented a hardware design method for the digital closed loop control system of FOG based on FPGA. Based on a large number of experiments, this paper summarized the parameter demands for each module of closed loop control circuit and designed a correspondin...
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 کاملDigital signal processing for an open-loop fiber-optic gyroscope.
Open-loop fiber-optic gyroscopes (FOG's) are generally less stable than closed-loop FOG's, yet they offer simpler implementation. We propose a modification of the harmonic division algorithm for an open-loop FOG, which is more stable and also simpler for implementation than the original one. It is shown that when the analog signal is properly sampled and quantized, the performance of our algori...
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 ...
