Measurement system for magneto-optic sensor materials

• A system for the measurements of magneto-optic properties of IR-transparent materials is described. The system is designed for the characterisation of fibre optic magnetic field sensor materials. Measurement results on YIG-crystals are prresented. The accuracy of Faraday rotation and light transmission measurements are ±2 mrad and ±2% respectively. Important features for the sensor characterisation are light beam scanning, temperature control and flexible magnetic field generation. A desktop computer is used for system control and data acquisition. The system is expected to be of great importance for future sensor developments.
