【Abstract】 The theoretical and experimental studies on the Direct Current Phase Tracking (PTDC) homodyne detecting system used in fiber optic Mach-Zehnder interferometer sensings are described in this paper. A set of experimental system is designed and constructed. And a sensitivity of 1 mrad has been achieved. The analysing and designing methods as well as the block chart of the experimental system are presented.更多还原
