| Abstract: | In this paper, theoretical and experimental studies on the Alternating Current phase tracking (PTAC) homodyne detecting system used in fiber optic Mach-Zehnder interferometer sensings are described. Operating condition suitable for PTAC detecting system is analyzed. A set of experimental system is designed and constructed. Sensitivity of the order of 10-4 rad has been achieved. |
