Electrooptic sensors and bio electromagnetism

  • Number of hours

    • Lectures 8

    ECTS

    ECTS 0,75

Goal(s)

The aim of this module is to give an overview of the existing techniques related to the electric field analysis within harsh environments. More precisely, this course will explain both the fundamentals of optical modulations in non-linear crystals and how to exploit this phenomena to develop suitable sensors. A focus will be dedicated to the influence of the ambient media on the sensor behavior. Examples of measurements in biological media and in ionized media with specific electro-optic sensors will be given.

The content of this lecture is based on state of the art research achievements. Nevertheless, the explanations will be adapted for the students of master WICS
