Paper Abstract

The object of these article is the conception, the realization and the used of a new imaging process based on the study of the polarization in the light-media interaction. In this investigation, a polarization-based imaging system is developed and described that measures the two-dimensional effective backscattering Mueller matrix of a sample. As is well known, a Mueller matrix can provide considerable information on the makeup and optical characteristics of a sample (depolarization,retardance, diattenuation...), but The reliability of measure and the reconstruction of the mueller matrix require the analysis of the error and the calibration of a Mueller polarimetre.Simulations enabled us, first, to determine the measurement error on each element of the Mueller matrix without a sample and, second, to adopt a method of calibration. therefore, the precision of experimentals results given by the Mueller matrix is drastically improved.The studies presented were performed with cancerous tissues and another non cancerous.The results demonstrate how these techniques could provide information that may be of diagnostic value in the physical detection of lesion.
