Abstract: An apparatus and method for determining an analyte concentration of a sample, such as a tissue sample. The apparatus may comprise an emitter, close proximity detectors laterally located less than about 2 mm away from the emitter, and far away detectors laterally located greater than about 0.5 cm away from the emitter. A plurality of wavelengths may be sent from the emitter to the sample, reflected off of the sample, and received by the detectors. The reflectance value measured by the close proximity detectors may be used to calculate one or more scattering coefficients. The reflectance value measured by the far away detectors may be compared with a reflectance value calculated using the scattering coefficients in a numerical inversion of a diffusion model to determine the analyte concentration of the sample.
