Reliability Evaluation Methods of Accelerated Degradation Test for Fiber-Optic Gyroscope Under Temperature Environment

نویسندگان

چکیده

Abstract Fiber Optic Gyroscope (FOG) is a kind of rotation sensor with high reliability and long lifetime. Accelerated life test hard to obtain enough failure data for evaluation. By analyzing mechanism, the sensitive environment stress performance degradation parameters FOG are determined. Then an accelerated (ADT) undertaken information. Wiener process introduced describe path Arrhenius model selected as model. Considering epistemic uncertainty in monitoring, interval linear regression ADT introduced. at operating evaluated. discussing assessment results, methods this paper feasible FOG.

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...

Evaluation 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...

Phase-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.

Large-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 ...

Digital 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...
