【Abstract】 A novel high voltage current fiber optic sensor is proposed. It is made up of the phase compress Sagnac interferometer. Compared with the common interferometers, this system has a large dynamic range extended thousands times, and is out of the effect of slow circumstance variables. The phase shifted technology makes the interferometer work at orthotronic interference state.更多还原
