Abstract
A method of enhancing the conversion of magnetic field intensity and spatial data to optical data utilizes surface plasmon resonance combined with corrugated optical gratings of several types. Appropriate materials and methods for producing and applying said corrugations and surface plasmon resonance-producing enhancements to Magneto-Optical Indicator Films (MOIF) are described. Methods of acquiring and interpreting magneto-optical data are also described.
