dc.description.abstractMagnetoencephalography, or MEG, is one particular technique of neuroimaging. It is a non-invasive and safe method of imaging the magnetic fields generated in the brain. There are currently a number of techniques developed for magnetic field sensing, including fiber-optic-based magnetic field sensors. Fiber optic sensors offer advantages due to their small size, low weight, and immunity to electromagnetic interference. This paper explains the current MEG neuroimaging system compared to alternative neuroimaging methods and addresses potential improvements using fiber optic sensors, such as magnetostrictive sensors. The advantages of these fiber-optic-based magnetic sensors over alternative magnetic field sensing techniques are explored. An experimental system is described, and a demodulation algorithm for the system is outlined. Finally, a theoretical analysis using magnetostrictive materials for MEG application is developed.
