Fiber optic interferometric circuit and magnetic field sensor
Abstract
A number of optical interferometric sensor configurations are provided. The interferometric sensors include a polarization maintaining optic fiber forming either a loop or linear optical path. Circularly polarized light propagate along the optical path and pass through a field-sensitive sensing medium. A differential phase shift induced in the light waves by a magnetic field is then detected by a photodetector and associated signal processing electronics.
