Electro-Optic Probe Devoted to Simultaneous Electric Field and Temperature Measurement in Biological Media for Dosimetric Assessments

Résumé

Here, we present the suitability of an electro-optic probe for performing simultaneous electric-field and temperature measurements in the case of bioelectromagnetic experiments such as specific absorption rate (SAR) assessments, or the characterization of in-situ nanosecond pulsed electric fields (nsPEF). In the frequency domain, the millimeter-sized probe, immersed in a water solution, reached a sensitivity of 170 mVm−1Hz1/2 , and presented a dynamic range exceeding 70 dB. Furthermore, temperature measurements led to a resolution of 22 mK. These abilities were used to perform dual SAR assessments by simultaneous electric-field and temperature measurements. Thanks to its ultra-wide bandwidth, the electro-optic probe is particularly suited for high transient electric-field measurements in the time domain. Pulses with different shapes and intensities were visualized and investigated.
