摘要：
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 and at least one broadband detector which measures the light signal transmitted through the tissue. 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.
