    Abstract: A near infrared spectrometer and method for wavelength and path length correction are disclosed. The spectrometer includes a number of photodiodes that transmit broadband near infrared measurement light into the tissue, at least one broadband detector which measures the light signal transmitted through the tissue, and at least one temperature sensor which senses at least one temperature of the number of photodiodes. A processor estimates chromophore concentrations through a comparison of measured light attenuation and modeled light attenuation. The light attenuation model utilizes a light path length distribution derived from a Monte Carlo model and accounts for the spectral shape of the light source as a function of temperature.
