In this paper we illustrate the ability of electrooptic sensors to perform electric (E)-field vectorial measurements. Thanks to their frequency response spreading over nine decades and to their measurement dynamics reaching 120 dB, these sensors are of high interest for some applications (near field mapping, energy line monitoring, electromagnetic compatibility, and so on). Furthermore, due to their fully dielectric structure and millimetric size, almost no perturbation is induced on the E-field to be measured, even in the near field region. This paper is focused on high-intensity pulsed E-field characterization in different environments such as air, water (bioelectromagnetism applications), or plasmas (in situ assessment of the E-field associated to an electric discharge and to the induced plasma). The use of such a technology for electrical equipment and energy line monitoring is also investigated. [ABSTRACT FROM PUBLISHER]

The complex-value electric field of a periodic phase-modulated optical signal is retrieved from the spectrogram/sonogram that is measured by a fast photodiode followed a tunable narrow-band optical filter. With an initial guess from the craters and ridges of the spectrogram, the numerical algorithm converges very fast to a mean-square error less than 1%. [ABSTRACT FROM PUBLISHER]
