Non-invasive research of biological objects by the method of laser polarimetry

Abstract

Recent studies have displayed that the biological tissue, especially skin, alters the polarization state of the incident light. Using this property will enable the study of abnormalities and diseases that change not only the light intensity but also its polarization state. This paper briefly considers spatial speckle-correlometry and polarimetry method for measuring changes of polarization state of the light scattered from a biological tissue. This technique provides the possibility to have the most comprehensive information on the optical and polarization properties of the skin sector containing scar structures and other abnormalities and diseases. Practical application of the developed approach is shown in the research.
