Current research at the fzmb deals with the development of a monitoring system for the continuous pH-measurement in vivo in the rumen of cattle in order to optimize the feed application and improve animal health in cattle farming. Here, an important aspect is the position of the pH-measuring bolus in the rumen. Within the scope of this work the movement pattern of the bolus depending on the bolus density (1.5-3g/cm3) was evaluated and recorded with a 3D magnetic monitoring system for 50 minutes during feeding. © 2014 by Walter de Gruyter Berlin Boston.

Magneto-optical imaging with magneto-optical indicator films (MOIF) is a versatile method to characterize magnetic field distributions especially for material development and quality control. Magnetic domains and grains in grain-oriented electrical steel can be visualized, and quantified without removing the isolation layer. The combination of MOIF with digital high-speed camera technology enables temporally resolved investigations of the magnetization processes. In contrast to Kerr-effect measurements MOIF imaging works without sample preparation and even in the presence of industrial insulation coatings. Optical resolution of 25 microns and temporal resolution of 1 ms in single-shot mode could be demonstrated. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Magneto-optical (MO) sensor technology offers entirely new perspectives in the field of magnetic measurement and testing. Parameter-measurement capabilities depend on sensor design, and are altered depending on the properties of the applied magnetic field. MO-sensors have the technical benefit of immediately obtaining measurement data directly above the surface of the magnetic material depending on the sensor size. Thus, real-time investigations of the magnet field distribution can be performed without the need for time-consuming, point-to-point scans. Illumination and detection taking place on the same side of the sensor provides a technical benefit where the functional side can be used for quick, easy test object positioning. MO-sensors can be saturated depending on the strength of the external applied magnet field. MO-sensors offer a wide variety of application opportunities for research tasks regarding magnetic domain analysis and investigation.
