Quantitative polarimetry Mueller matrix decomposition approach for diagnosing melanoma and non-melanoma human skin cancer

A simple and effective polarimetric technique is used to discriminate benign lesions from cancerous ones. This method is based on key polarimetric parameters of diattenuation, depolarization, and retardance. Several samples of human skin exhibiting three kinds of cancer as well as benign specimens are examined using a polarimetric technique and results are compared with pathology diagnosis. In this study polarimetric parameters are taken into account as a reliable diagnostic tool to distinguish the cancerous lesions precisely and non-invasively.
