TL;DR: In this article, a multi-wavelength time-domain near-infrared spectroscopy (TD-NIRS) system was proposed for muscle and brain oxygenation monitoring in a clinical environment.

TL;DR: It is shown that a multi-wavelength time-resolved data can be used for parameters recovery directly without prior calibration (instrument response function measurement) and that parameters recovery compared to the conventional curve fitting approach is within 10% and benefits from introducing a spectral constraint to the reconstruction problem.

TL;DR: The results demonstrate that the flickering frequency had a statistically significant effect on the induced oxyhemoglobin changes and demonstrated superiority of 8 Hz over other frequencies, which can advance understanding of visual stimulations and help guide future fNIRS protocols.

TL;DR: A method that allows analysis, quantitative comparison and performance ranking of measurands under various conditions - including different values of reduced scattering coefficient, thickness of the superficial layer, and source-detector separation is implemented.

TL;DR: A novel methodology for solving the inverse problem of diffuse optics for two-layered structures is proposed to retrieve the absolute quantities of optical absorption and reduced scattering coefficients of the layers simultaneously simultaneously to improve the reliability and uncertainty of the retrieval performance.
