In spite of many progresses achieved both with theories and with experiments in studying light propagation through diffusive media, a reliable method for accurate measurements of the optical properties of diffusive media at NIR wavelengths is, in our opinion, still missing. It is therefore difficult to create a reference diffusive medium. We describe two methods in the CW and time domain to calibrate the reduced scattering coefficient of a liquid diffusive medium and the absorption coefficient of an absorber with a standard error smaller than 2% for both the coefficients.

Abstract
In spite of many progresses achieved both with theories and with experiments in studying light propagation through diffusive media, a reliable method for accurate measurements of the optical properties of diffusive media at NIR wavelengths is, in our opinion, still missing. It is therefore difficult to create a reference diffusive medium. We describe two methods in the CW and time domain to calibrate the reduced scattering coefficient of a liquid diffusive medium and the absorption coefficient of an absorber with a standard error smaller than 2% for both the coefficients.File | Dimensione | Formato | |
