摘　　要：根据实际需要优化设计了一种基于啁啾布喇格光栅的本征型光纤法珀(F-P)传感器。对构成光纤F-P传感器的啁啾布喇格光栅的参数进行了优化设计,得到优化设计的光纤F-P传感器反射谱。实际制作了按照参数设计的啁啾布喇格光栅F-P传感器并进行了应变实验,实验结果表明,该方法设计的传感器应变测量精度高达±8με。An optimized fiber-optic Fabry-Perot sensor with a long cavity based on two chirped fiber Bragg gratings （CFBG） with same wavelength and bandwidth is proposed. The parameters of CFBG and Fabry-Perot sensor are optimized. According to the optimized parameters, an optimized Fabry-Perot sensor is formed. The strain experiment using optimized Fabry-Perot sensor has been carried out. The experimental results show that a strain accuracy of better than ±8με is achieved.
