The vector structure of laser biospeckle fields and polarization diagnostics of collagen skin structures

The transformation of the polarization and correlation structure of low-intensity laser radiation by skin is considered. The method of matrix modeling of optical properties of skin epidermis and derma is proposed. This approach is employed to analyze the mechanisms behind the transformation of the polarization state of scattered laser radiation field and the formation of an ensemble of coherent biospeckles. The technique for the polarization diagnostics of the structure of the collagen network in skin derma is proposed.
