摘要 从原理上分析了光栅透射谱对偏振相关损耗测量的灵敏度、测量范围和检测难易度等多个性能指标的影响机理,并利用传输矩阵法对各种光栅结构的传感性能进行了比较分析。为了降低检测误差,利用分立层剥重构算法分析了透射功率谱为级联三角形的光栅结构。为基于光栅偏振特性的传感测量中光栅结构的选择提供了参考。 The influence of transmission spectrum on the sensor characteristics including sensitivity,dynamic range and detecting is discussed,and the comparisons of sensor characteristics are realized using the transfer matrix method.In order to decrease the detecting error,the fiber grating with cascaded triangular transmission spectrum is designed by using discrete layer peeling (DLP) algorithm.Some design principles of grating structures in sensors based on the polarization dependent properties of the fiber grating are provided.
