Abstract

For resolving concentrations of tissue chromophores in the human adult brain with near-infrared spectroscopy it is advantageous to calculate the light scattering and absorption, at multiple wavelengths with some depth resolution. We report a novel methodology that combines multi-distance frequency and broadband spectrometers and we show preliminary results in a healthy young adult during hypo- and hypercapnia.
