Abstract
We report first a new derivation of the scattering phase theorem and provide, for the first time, the correct relation between the variance of phase gradient and the reduced scattering coefficient. The scattering-phase theorem is then applied to investigate bulk light scattering property from the phase map of thin slices of tissue phantoms measured by a differential phase interference (DIC) microscope using the intensity propagation equation approach. The scattering coefficient, the reduced scattering coefficient, and the anisotropy factor of the sample obtained with this approach is compared to known scattering property of the bulk samples.
