Magneto-Optic Imaging: The Technique |
| Magneto-optical contrast is based on the Faraday rotation of polarized light that is induced in magneto-optically active materials. A thin film of magneto-optical material placed in contact with a magnetized sample will respond locally to the magnetic field generated by the sample that is under study. Any non-uniform field in the sample will cause non-uniform rotation of the polarization vector of the incident light, and therefore contrast in the polarized light image. |
