Wavelength-dependent, polarized, elastic-scatter spectra of tissue phantoms
and in vitro tissue are presented. These measurements are shown to be sens
itive to very small changes in composition of the scattering medium. A simp
le physical explanation of the wavelength-dependent polarization phenomena
observed for media consisting only of spherical particles is given and the
relevance of wavelength-dependent, polarized, elastic-scatter spectra to in
vivo applications is discussed. (C) 1999 Optical Society of America.
