摘要
激光器驱动电源的稳定性直接影响反射强度调制式光纤传感器的测量精度和寿命。以嵌入式系统为数字控制核心,PID为控制调节算法,建立激光器的温度和光强补偿系统。用设计的补偿系统对1310 nm波长的激光器进行试验研究,结果表明该反馈补偿系统能使反射式光纤传感器的精度和稳定性得到较大的提高。
Laser-driven stability has a direct impact on the power reflection intensity modulated fiber optic sensor＇s measurement accuracy and life.To embedded system for the digital control core, PIDalgorithm to control the regulation,the laser temperature and light intensity compensation system is established. The 1310 nm wavelength laser is studied with the eompensationsystem. The results show that that feedback compensation system makes reflective fiber optic sensor accuracy and stability tobe enhanced.
