Fiber optic gyroscope (FOG) is a kind of high precision angular rate sensor which is highly affected by environment temperature. Research on FOG temperature error is meaningful for improving its environmental performance. In this paper, a simplified FOG output error model is presented by using reduced discretized parameters. Simulation results show the residual error and computational complexity of...
In practical applications of fiber optic gyroscope (FOG), the impact of shock on FOG precision should be considered, especially under the condition of explosion. To improve the performance of FOG in shock environment, a key issue is fixed the fiber coil well. Besides, the fiber tail of the Y waveguide as well as the fiber coil is also an important factor which will influence the shock performance...
The performance of fiber optic gyroscope (FOG) exhibits temperature dependence due to nonreciprocity phase shift in the fiber coil induced by environmental temperature variation. Research on temperature characteristic is meaningful for high precision FOG working in harsh environment. In this letter, modeling of thermal-induced rate error for FOG with environmental temperature ranging from ...
