Electro-optics as a versatile technique for non-invasive vectorial sensing of electric fields

We here present the most recent advances in electro-optics (EO) dedicated to non-invasive characterization of electric (E) fields. We develop E-field sensors exploiting the Pockel's effect (E-field induced linear variations of refractive indices for EO crystals). These pigtailed transducers are fully dielectric. While the sensitivity reaches 1 V.m−1. Hz−1/2, the bandwidth covers more than 8 decades of frequency. The spatial resolution is greater than 100 μm. A complete analysis of these sensors will be presented as well as some examples in different research areas: 2D mapping of guided waves, transient evolution of disruptive E-Field, SAR measurements in biologic media, …
