摘　　要：设计了一种基于超辐射发光二极管(Super Luminescent Diode,SLD)光源的三轴光纤陀螺组合光路检测系统。同步使用温控和恒流驱动电路保证SLD全温范围内的正常工作,电源部分进行防浪涌设计,有效避免开关电源或环境变化引起的瞬态冲击,达到对器件的保护效果。检测系统通过对有光和无光情况下的光电探测器输出偏置电压进行监测,同时通过数值分析计算出装配完成的光路系统损耗,以此判断光纤陀螺光路技术指标是否满足设计需求。最后,实验验证了三轴光纤陀螺组合光路检测系统在产品批量化生产过程中的作用,使光纤陀螺的精度稳定性达到了87%,成品性能合格率提升至96%。This paper presents the design of a three-axis fiber optic gyro combined optical path detection system based on a Super Luminescent Diode(SLD)light source.The system employs synchronized temperature control and constant current drive circuits to ensure normal operation of the SLD across the full temperature range.The power supply section incorporates surge protection to effectively prevent transient impacts caused by switching power supplies or environmental changes,thus protecting the components.The detection system monitors the photodetector's output bias voltage under both light and no-light conditions,while simultaneously calculating the assembled optical path system loss through numerical analysis.This approach determines whether the fiber optic gyro's optical path technical specifications meet the design requirements.Finally,experimental validation demonstrates the effectiveness of the three-axis fiber optic gyro combined optical path detection system in batch production processes.The system improved the accuracy stability of fiber optic gyros to 87%and increased the finished product qualification rate to 96%.
