摘　　要：利用矩阵法和编程计算,对λ/4相移光栅在外界应变或温度的影响下,其反射光谱特性进行研究,得出一些规律性的结论.这些理论结果将对相移光栅在传感中的应用及其制作有参考作用.Using the matrix approach and Mathematica calculation,the main reflective spectra character of λ/4 phase-shifted fiber grating was analysed with the conditions such as strain and temperatures changed and draw some disciplinary conclusions. These theoretical results have important instruction for the fabrication of phase-shifted grating and its application in sensors.
