Abstract :
This paper describes firstly the design and the characterization of pigtailed electro-optic (EO) sensors based on Pockels´ effect, particularly appropriate for non invasive electric (E) field measurements. Afterwards we present transient and frequency characterization of a microwave guided field. Last experiments concern the ability of EO probes to measure a non recurring single shot microwave field compared to antennas. We also provide an assessment of the disturbance induced by the sensors to the field to be measured, using an infrared thermography technique. Sensors based on polarisation state and on amplitude modulation will be presented and compared to alternative techniques during the conference
