| 摘 要： | 提出了一种基于光子晶体光纤Sagnac干涉仪的横向压力传感器。使用的光子晶体光纤为低双折射光纤，首先预先在Saganc环中的光子晶体光纤上施加初始压力，使Sagnac干涉仪产生正弦干涉光谱，然后再将被测物体放在光子晶体光纤上，由于被测物体重力的作用，Saganc干涉仪输出的光谱产生移动，实现横向压力传感测量。传感器具有高灵敏度0.529 nm/(N·mm)及超低的温度系数-0.4 pm/℃，其环境温度的影响可以忽略。

| Abstract: | A lateral force sensor based on low birefringence photonic crystal fiber Sagnac interferometer is proposed. The sinusoidal interference spectrum is produced due to the initial lateral force which is pre-applied on the low birefringence fiber. The load placed on the fiber introduces extra birefringence and corresponding spectrum shift for measurement. The sensitivity achieved is 0.529 nm/(N·mm). The property of temperature-insensitivity is verified in the experiment with the temperature coefficient of -0.4 pm/℃ which can be neglected. |
