Paper Abstract

The interaction of light with tissue and cells is the underlying mechanism for optical biomedical imaging and spectroscopy to detect pathology changes. We use fractal continuous random media to model visible and near infrared light scattering by biological tissue and cell suspensions, which provides a simple relation between the morphological features of the sample and its optical properties (absorption, scattering and anisotropic factor of light scattering). Good agreement with experimental results are found for this fractal continuous random medium model. A novel optical biopsy scheme of oblique incidence Fourier reflectometry is proposed for spectroscopic tissue diagnosis based on the model.
