Mueller matrix has a vast application regarding information of any scattering (turbid) media such as fog, sea water, and biological tissues. It can extract information from scattering properties of the medium. Recently, information from Mueller images and their interpretation are being used for diagnostic purposes in biological tissues. Polar decomposition of Mueller matrices for scattering medium have also been developed, which could be a very powerful and sensitive tool for mapping the morphology of human tissue sections. On the basis of such decomposition, we report here the variation of diattenuation, depolarization and retardance from normal to dysplasia state in cervix tissue.© (2008) COPYRIGHT SPIE--The International Society for Optical Engineering.
