Abstract :
Broadband (30-1000MHz) frequency modulated spectroscopic measurements of brain tissue using near IR wavelengths are used for accurate extraction of absorption and scattering coefficients of cortex, CSF, and skull. Design of a helmet mounted untethered functional near IR system is presented in this paper that provides wireless communication between the monitoring and helmet mounted fNIR imaging sensors using high speed wireless ISM band Transmitter and UWB communication standards. Design specifications and predicted performance requirements are presented of the custom designed low power consuming optical transceivers and wireless communication subsystems using IBM 90nm CMOS foundry parameters.
