Mueller matrix polarimetry for differentiating characteristic features of different materials (wood, shinning steel, unpolished plastic)

Polarization measurements improve the imaging contrast by using various samples (wood, shinning steel, unpolished plastic). For better explanations of the micro- and macro-structures and basic characteristics of the materials, we perform Mueller matrix imaging on various samples, expressed by the characteristic features of the
$3\times 3$
Mueller matrix elements. This research gives new ideas for various samples on the contrast mechanisms of Mueller matrix components, which can provide new diagnostic techniques for biomedical applications.
