Abstract

Equiintensity contours of photometric patterns of focused linearly polarized light (650 nm) were fitted with ellipses that appeared to follow the orientation of collagen fibers. The ratio of the ellipses semi-axes is well correlated with the ratio of reduced scattering coefficients obtained from intensity profiles. The mapping of the polarization degree shown that for skin and collagen based phantom it may preserved up to 1.5-2.5 mm distance from the probe beam injection.
