Abstract

The absorption and the reduced scattering coefficients of living tissues were obtained from measurements of time-resolved reflectance at near-IR wavelengths. The inversion procedure was based on the temporal spread function for a semi-infinite medium given by the diffusion approximation. Measurements showed significant variations between the optical parameters measured on different organs and different volunteers. The single scattering properties (extinction coefficient and scattering function at small forward scattering angles) of bovine and swine brain were obtained from transmissometric measurements on thin slices of tissues. Large differences between the optical properites of white and grey matter were observed, whereas minor differences were found between bovine and swine samples.
