Fiber Optic DC Magnetic Field Sensor with Alternating Current Phase Tracing

摘要：

A sensitive DC magnetic field sensor based on magnetostrictive straining of optical fibers was demonstrated,which utilizes alternating current phase tracing (PTAC) homodyne scheme to eliminate phase drift. Comparison was carried out experimentally between direct current phase tracing (PTDC) and alternating current phase tracing,then expressions were presented. The results showed that the PTAC had better performance both in stabilization and linearity.
