Abstract : A fiber optic interferometer sensor system utilizing a fiber optic interferometer with an elecrostrictive transducer bonded to one of first and second optical fiber arms of the interferometer for obtaining excellent low frequency voltage detectors and electric field sensors. The non-linear characteristics of the electrostrictive transducer allows for detecting low frequency or dc signals at sidebands of a high frequency carrier, resolving extremely small voltages at low frequencies, or sensing low frequency electric fields. Examples of electrostrictive material include Ba:PZT, PLZT, PMN+PT, and other doped ferroelectric relaxors. (AN)
