Abstract
We present a method for the detection and localization of inhomogeneit ies embedded within highly scattering media that employs speckle stati stics with a partially coherent light source. Variations in speckle co ntrast as a function of position are used to interrogate inhomogeneiti es deeply embedded within scattering media. A numerical model based on photon diffusion theory is introduced to predict speckle contrast as a function of scan position. This model uses measured speckle data to determine scattering and absorption parameters. (C) 1997 Optical Socie ty of America.
