Abstract

An electric/optical (E/O) probe system for measurement of in-body field strength at 85 kHz is proposed. The proposed system uses an optical modulator in order to avoid interference of conducting cables. An impedance matching circuit between the optical modulator and probe in lossy human body is designed to enhance sensitivity of the system. The field strength in a liquid human phantom is measured by using the designed E/O probe system at 85 kHz. It is demonstrated the sensitivity of the probe increases by implementing the impedance matching circuit.
