Optical properties of tissues quantified by Fourier-transform light scattering

We employ Fourier-transform light scattering, a technique recently developed in our laboratory, to study the scattering properties of rat organ tissues. Using the knowledge of the complex field associated with high- resolution microscope images of tissue slices, we extracted the scattering mean-free path l_s and anisotropy factor g, which characterize the bulk tissue for three different rat organs. This "bottom up" approach to measuring tissue scattering parameters allows for predicting the wave transport phenomena within the organ of interest at a multitude of scales - from organelle to organ level.
