| 摘 要： | 针对布里渊光纤陀螺动态范围较小的问题,在比较了以往各种方案动态范围的基础上,提出了一种基于光强补偿的布里渊光纤陀螺动态范围增大方案.该方案使用大功率窄带激光器做泵浦源,在光路中引入光衰减器以及分光比不对称的耦合器,并通过反馈回路对两路光光强进行实时调节,从而可以消除泵浦游走效应对布里渊光纤陀螺动态范围的影响.通过分析和...

| Abstract: | The dynamic range of Brillouin fiber optic gyroscope is narrow.To solve this problem,a new scheme based on light intensity compensation was designed after comparing most of the past methods.This scheme adopts the following measures to removes the influences of pump walk-off effect: High-power narrow-band laser was used as the pump source;The light path applies light intensity attenuator and the coupler with unbalanced intensity coupling coefficients;and the light intensities of the two paths were real-time ... |
