UWB wireless link design and implementation challenges in broadband frequency modulated fNIR biomedical imaging

Abstract

Functional spectroscopic measurements of brain matter using near IR wavelengths are characterized by absorption coefficient μa and scattering coefficient μs. To increase the accuracy of parameter extraction, a broadband frequency modulated system is proposed and design and implementation challenges of a completely untethered and field deployable unit and a high speed wireless communication system is considered to complement a free space optical communication system.
