Besides developing highly sensitive atomic magnetometers, we also use alternative (cheaper, simpler, more compact, less performant) magnetometric devices in view of several different applications. In particular, we developed instrumentation based on multiple magnetic sensors arranged in array, to localize and characterize small-size magnetic sources. This applied research has important implications for the development of medical diagnostics and, more generally, for biomedical research, assistive technologies, and human-computer interaction.
As an example, this research led us to build an innovative eye-tracker that enables us to simultaneously record eye and head rotations. The latter feature has implications for analyzing the vestibulo-ocular reflex and constitutes an interesting opportunity to develop medical tools for oto-neurological diagnostics.
