Abstract

A set-up for time-resolved transmittance and reflectance spectroscopy of diffusive media was upgraded to allow measurements to be performed continuously from 600 to 1100 nm. Time-resolved diffuse optical spectroscopy of breast was carried out on 10 healthy volunteers, demonstrating the feasibility of <i>in vivo</i> measurements up to 1100 nm. The optical characterization of collagen was also extended revealing an absorption peak (around 1020–1030 nm), which could prove of interest for the <i>in vivo</i> quantification of collagen.
