对一种基于强度补偿的自由式光纤束差压传感器进行设计与研究。传感器探头部分采用同结构、双探头的设计,传感器探头采用机械式封装；对传感器的光纤部分进行了强度补偿设计与分析,并利用调制函数 M,理论分析了补偿后的输出值 R；在对两传感探头施加相等的压力 p =20 kPa 情况下,改变光源的输出功率,测出光电探测器的输出电压值,并在两探头存在不同的压差△p 时,测出其输出值R。实验结果表明：通过强度补偿后,输出值R ≈1,同时在不同的压差作用下,输出值R 与压差△p 在一段区域内有较好的线性关系。研究结果表明：传感器的强度补偿效果明显,可实现压力差值的检测。

A kind of freestyle optical fiber bundle differential pressure sensor based on intensity compensation was designed and researched.Firstly,the sensor probe part was designed with double probe and the same structure,and was packaged by mechanical style.Then,the sensor fiber part was designed and analyzed on the intensity compensation,after the compensation,the output value of R was analyzed theoretically with the modulation function M.Finally,R was tested out under different conditions,changing the output power of the light source when there is same pressure p =20 kPa in two probes,or inputting different pressures in two probes.Experimental results show that:through strength after compensation,the output value R≈1,at the same time under the influence of different pressure differentials,the output value R and pressure difference △p within a certain area is of a good linear relationship.Through the above research it is proved that the effects of intensity compensation are obvious and can detect pressure difference.
