光纤法珀应变传感器的算法改进

Improved algorithm of fiber Fabry-Perot strain sensor

绝对光纤法珀应变传感器(AEFPI)已经在工程结构监测中得到了应用。本文对传统AEFPI的算法进行了分析,并提出了一种改进算法,仿真的结果证明了传统算法只是该算法的一种特例,而该算法在不改变任何硬件的情况下,能够显著的降低系统的测量误差。

Absolute optical fiber Fabry-Perot strain sensor （AEFPI） has been monitoring in engineering structures has been applied. In this paper, traditional algorithm AEFPI analyzed, and presented art improved algorithm, simulation results prove that the traditional algorithm is that the algorithm is a special case, and the algorithm does not change any hardware in the circumstances, can significantly reduce system measurement error.
