摘要
结合光纤陀螺光源驱动的特点,设计了高精度恒流源及精密温控、光控电路,用于驱动光纤陀螺光源。测试结果表明,在环境温度-20℃～+60℃内,恒流精度优于0.01%,温控精度达到0.01℃,输出光功率的变化在0.04%以内,较通用的光源驱动电路提高了一个数量级。
The stability of the light source is a key factor affecting the precision of Fiber-Optic Gyroscope(FOG). Considering the characteristics of driving of the light source of FOG,the precise constant current source,temperature con-trol and light power control are designed.The testing results indicates that,while in a ambient temperature range of -20℃～+60℃,the presented technology can yield a current precision as high as 0.01%,a temperature control precision of 0.01℃,and a variety of light power less than 0.04%,with improvement of more quantitive level than the conventional driving cir-cuit of the light source.
