Abstract

In this paper, we apply Mueller polarimetry to study different samples of porous media compacted as tablets from a pharmaceutical excipient microcrystalline cellulose. We measured the Mueller matrices of the samples with the home made polarimeter using a He-Ne laser (0.63 μm). We show that polarization entropy manifests the highest sensitivity to the porosity allowing to identify the tablets of different porosities.

Author Biography

  • S. N. Savenkov, Radiophysics dep., Kiev National Taras Shevchenko University

    Sergey N. SAVENKOV was born in 1964. He received his M.S. in Kiev Taras Shevchenko university in 1986. His Ph.D. thesis was in the field of investigation of information possibilities of polarization measurements. His research interests are focused on the study of information possibilities of polarization of electromagnetic radiation in remote sensing, crystal optics, biomedical optics and in laser radar. Specific topics are an analysis of structural and anisotropy properties of objects contained in their Mueller matrices, development of the Mueller matrix measurement methods, optimization of polarimetric sensors for remote sensing applications, and use of polarimetry to improve imaging in scattering media.

    He is an author more that 100 publications (PhysRev, JOSA, ApplOpt, JQSRT etc.) including 3 book’s chapters (Springer).
