Key technology and application prospect of the one-fiber fiber-optical gyroscope

The one-fiber FOG is one of FOG, it is low-cost, high reliable and prone to realization in engineering. It is turned out by means of in-line manufacturing technologies to produce optical parts on one fiber, thus to form a circuit without weld joints. This in-line manufacturing technologies includes fiber annulus winding, the produce of couplers, polarimeters, luminescence modules, receiver modules and so on. The definition, principles, key technologies and manufacturing procedure of the one-fiber FOG are introduced, and the measures to improve its performance are presented. The application prospect of the one-fiber FOG is prefigured on the base of the analysis of the performances of the one-fiber FOG series.With the developing of the one-fiber FOG manufacturing technologies and the increasing perfection of signal processing, the performances of the one-fiber FOG are improved further, and the cost is reduced gradually, it is helpful to accelerate the prevalence and application of the one-fiber FOG.
