Abstract
Alterations in tissue morphology and composition will result in detectable changes in the way light
is transmitted, refracted, diracted, or reected from a given tissue specimen. Experimental measurements, such as light scattering intensity and its angular dependence, can be used to infer changes in
size/shape or refractive index of the specimen under study. Biological analysis methods based on elastic
