摘　　要：为提高光纤陀螺准确度、实现工程化应用,分析了SLD光源内部的热结构,建立了全数字光源控制系统.测试结果表明:在变温环境下(-15℃～55℃),抑制了光源的“交越失真”现象,实现了光源平均波长波动0.014%,光功率波动0.4%的控制准确度.采用抑制交越失真控制的光源的FOG在全温度范围内的零偏稳定性从2.14°/h提高到0.21°/h.For the purpose of improving precision and practicability of Fiber Optic Gyroscope, the thermal fabrication of SLD module was analyzed and a detailed description of the all-digital control system had been carried out. The testing result indicated that in a temperature range of -15℃ to 55℃, it restrained the temperature fluctuating of SLD. This technology yielded a much better stability of SLD＇s wavelength 0. 014% and output power 0.4℃,which conduced to a much better performance of FOG.
