Abstract:

THE DEVELOPMENT OF A NON-INTRUSIVE ELECTRIC FIELD SENSOR BASED ON THE ELECTRO-OPTIC EFFECT IS PROPOSED. ELECTRO-OPTIC CRYSTALS ARE SELECTED SUCH THAT A DIFFERENCE IN THE INDEX OF REFRACTION ALONG THE PRINCIPAL OPTICAL AXES, INDUCED BY A CHANGING ELECTRIC FIELD, RESULTS IN A CHANGE IN TRANSMISSION THROUGH THE OPTICAL SYSTEM. THROUGH THE CHOICE OF AN APPROPRIATE CRYSTAL AND CRYSTAL GEOMETRIES, VARIOUS SENSITIVITIES AND AC BANDWIDTHS ARE ATTAINED IN A FIBER OPTIC SENSOR. THE NATURE OF THE ELECTRO-OPTIC EFFECT EXHIBITED IN ELECTRO-OPTIC CRYSTALS SELECTS SENSITIVITIES TO THE ELECTRIC FIELD ONLY IN ONE DIRECTION. THEREFORE, A SENSOR CAN BE DEVELOPED WITH 3 ELECTRO-OPTIC CRYSTALS MOUNTED ORTHOGONALLY SUCH THAT BOTH FIELD STRENGTH AND DIRECTION CAN BE DETERMINED. ALSO, THE ELECTRONICS AND SIGNAL PROCESSING EQUIPMENT ARE LOCATED AT A GREAT DISTANCE FROM THE SENSOR END, ALLOWING FOR REAL TIME ELECTRIC FIELD MEASUREMENTS IN HOSTILE ENVIRONMENTS. PHASE I RESEARCH IS DIRECTED AT THE SELECTION OF SUITABLE ELECTRO-OPTIC CRYSTALS FOR DESIGNING FIBER OPTIC SENSORS AND TOWARDS THE DETERMINATION OF OPTIMUM MEANS OF SIGNAL DETECTION.
