Fiber 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 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.
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 کاملEvaluation of Ring Laser and Fiber Optic Gyroscope Technology
In past years much interest has been shown in the development of optical gyroscopes which offer the potential of solid state, highly reliable performance immune from many of the mechanical effects which restrict the performance of conventional spinning mass gyroscopes. Both ring laser and fiber optic gyros operate by sensing the difference in propagation time between beams of light traveling in...
متن کاملScale-factor-stabilized fiber-optic gyroscope by deep phase modulation.
A scale-factor-stabilized fiber-optic gyroscope by deep phase modulation is demonstrated. There are two servo loops included in this system. The first servo loop is used for stabilization of the light intensity output of the fiber-optic gyroscope. The second loop is used to stabilize the phase-modulation index. The third-harmonic frequency of the phase-modulation signal is used for detection of...
