Near-infrared light (NIR) can propagate through tissues and at particular wavelengths is differentially absorbed by oxgenated vs. deoxygenated forms of hemoglobin and myoglobin. Illumination of intact tissue with NIR allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition. |
