摘要: A new method of signal analysis from a polarimetric optical fiber sensor is presented. The proposed based on the Hilbert transform and utilizes only one light detector to calculate strain-induced phase shift, thereby overall cost complexity minimized. demodulation algorithm optimized for dynamic strain measurement used in composite materials monitoring. implemented measure reflective configuration. Vibration mechanical impact measurements as well Fourier prove reliability method.
