The quantitative measurement of the electric field is a demanding task that has to be accomplished without perturbing the spatial distribution of the field itself and by using systems that can be operated safely also when intense electric fields have to be measured. In this paper it is presented an innovative fully dielectric electro-optic sensor suitable for measuring electric field in the range 150 V/m÷1 MV/m. An application example: the electric field shields characterization will be presented as a novel application.
