Evaluation of the mechanical properties biological tissues has always been an important issue in field biomedicine. The traditional method for measurement is to perform vitro tissue deformation experiments. With fast development optical and image processing techniques, more non-invasive non-contact methods have applied analysis features. In this study, we use Mueller matrix polarimetry quantita...

Spectral Mueller matrices measured at multiple angles of incidence as well as Mueller matrix images are recorded on the exoskeletons (cuticles) of the scarab beetles Cetonia aurata and Chrysina argenteola. Cetonia aurata is green whereas Chrysina argenteola is gold-colored. When illuminated with natural (unpolarized) light, both species reflect left-handed and near-circularly polarized light or...

Linear birefringence and optical activity are two common optical polarization effects present in biological tissue, and determination of these properties has useful biomedical applications. However, measurement and unique interpretation of these parameters in tissue is hindered by strong multiple scattering effects and by the fact that these and other polarization effects are often present simu...

In this paper, we report the significance of double Stokes–Mueller polarimetry (DSMP) technique, to characterize a large size (3×3×5mm) Potassium titanyl phosphate (KTP) crystal. The crystal undergoes second harmonic generation with type II phase matching. study standard KTP using DSMP technique helps validate efficiency technique. We were able extract crystal’s Mueller matrix, relative contrib...
