Abstract

Statistical functions help judging optical parameters estimation (absorption μa and diffusion μs') at different experimental conditions. We show that the reduced χ² function is a powerful tool for judging goodness of fit and finding fitting interval, providing enough photons are acquired. Situations of small scattering or strong absorption, small interfiber distance, surface influence and fit boundaries influence with both infinite and semi-infinite diffusion model are analyzed together with the above statistical tools to judge the estimation. ©2009 Optical Society of America
