摘要 采用可调光纤F-P滤波器技术设计了一种光纤光栅加速度传感系统。提出了一种温度补偿型光纤光栅加速度传感探头,探头弹性系统主要有惯性质量块、双弹簧片、钢管等组成。探头采用不受力光纤光栅法进行了温度补偿。该探头具有结构简单,不受电磁干扰,不受光路功率波动和相位噪声影响等优点,且能自动进行温度补偿。 A fiber Bragg gratings vibration acceleration measurement system was designed by using the tunable Fabry-Perot filter technology.A temperature compensated fiber Bragg gratings acceleration sensing probe was proposed in this work.The elastic system of the sensing probe was composed of an inertial mass block,dual spring and steel pipe.The fiber Bragg grating free of strain was used to compensate the temperature of probe.The proposed sensing probe has the advantages of simple structure,being free from the electromagnetic interference,optical path power fluctuation and phase noise,and being realized temperature compensation automatically.
