基于kolmogoroff方法重构光纤光栅相位响应

Phase Reconstruction of Fibre Gratings Based on Kolmogoroff Method

借用信号处理的kolmogoroff方法,在最小相移的前提下,由光纤光栅的强度响应谱重构相位响应及冲激脉冲响应,由此确定时延、色散以及光纤光栅的某些结构特征。以均匀光纤光栅为例,证明该方法是行之有效的。

On condition of minimum-phase shift, the phase response spectrum and impulse response of fibre gratings can be reconstructed from its intensity response spectrum based on Kolmogoroff method which appears in signal processing field, then time-delay, dispersion and some structural features can be determined. And uniform fibre grating is used as exemplification to validate this arithmetic.
