光纤陀螺及其发展动态

Fiber Optic Gyroscope and Its Development

迄今为止,光纤陀螺的发展已经经过了三个时期,第一代为干涉型光纤陀螺(I-FOG),第二代为共振环形腔型光纤陀螺(R-FOG),第三代为受激布里渊散射光纤陀螺(B-FOG)。简要陈述了光纤陀螺的发展历程,并着重阐述了这三种光纤陀螺各自的工作原理、噪声特性及今后的发展动态。

Fiber optic gyroscope(FOG) has been pass through three generations, the first generation is interferometric FOG(I-FOG), the second generation is resonance loop cavity FOG(R-FOG) and the third generation is stimulated brillouin scattering FOG(B-FOG).The developing course of the FOGs has been delivered concisely, then the principles, noise characteristics and future developing trends has been expounded.
