Abstract

The present invention relates to the differential detection of directly backscattered light from epithelial tissues in order to determine the cell nuclear size distribution for the purpose of detecting tissue dysplasia. Light directly backscattered from surface tissue is differentiated from the light backscattered from underlying tissue by means of polarization, angular distribution or both. Both point measurement embodiments and imaging embodiments are presented. Optical systems for delivery and collection of light include endoscopic and fiber optic systems.
