Medical Optics and dynamic light-scattering are basic theory of Near infrared spectroscopy (NIRS) for living tissue. Light propagation is described by optical diffusion equations. The equation has two parameters, diffusion coefficient and absorption coefficient. The Lambert-Beer law is used for Spectroscopy. Spectroscopy measures optical density and calculates concentration.The actual NIRS system is based on the modified Lambert-Beer law.We should know the specifications of the device in order to apply to functional research of the brain.
