Abstract: | The polarization fading of unbalance fiber Mach-Zehnder interferometer used for demodulating the signal of N-element fiber grating sensor array is investigated. With the Poincare sphere and the optical wave-guide theory, the theoretical model is simplified. Through the theoretical analysis, the expression of visibility lower limit for the minimum visibility of N-element sensor array under optimum control is got. The result of the cyber-simulation experiment testifies the expression. At last, the result of cyber-simulation experiment is analyzed. |
