Summary: This work presents a simplified cylinder-birefringence optical model of the human skin dermis and measures the polarization parameters of human fingernail skin. The accuracy and stability of the Mueller matrix polarization decomposition (MMPD) and the direct Mueller matrix (DMM) methods are compared under different incident and scattering angles. A significant contribution of this study is the use of a polarization-sensitive optical coherence tomography device to obtain the value of birefringence of the skin dermis from living human index finger nail images. The results provide a basis for selecting incident and scattering angles when measuring biological samples with fibrous structures in the future.

Summary: Mueller matrix polarimetry quantifies changes in polarization of light beam through a sample, but multiple polarization effects occurring simultaneously in tissues can hinder unique interpretation. Various decomposition schemes, such as Mueller matrix transformation and Mueller matrix differential decomposition, are used to untangle these effects. Comparing these two methods for tissue and phantom samples revealed consistent total depolarization values but significant differences in total retardance. Linear fitting of the scatter plot showed good correlation between corresponding polarization parameters of the two methods.

Summary: This new method allows for directly obtaining polarization properties from measured macroscopic Mueller matrices without the need for decomposition. By analyzing the canonical decomposition form of macroscopic Mueller matrices, the method accurately derives the parameters representing polarization and depolarization properties of a medium. The theoretical validation demonstrates the high accuracy of this method in extracting polarization properties from measured Mueller matrices.

Summary: A Mueller matrix can characterize the polarimetric properties of a medium, and parameters like depolarization, retardance and diattenuation can be obtained through decomposition methods. The introduction of a simplified 3 x 4 Mueller matrix and decomposition algorithm provides an effective way to measure and characterize samples, calculating properties such as depolarization, retardance and orientation.

Summary: In this paper, a fast-backscattering Mueller matrix imaging system was established to quantitatively probe the dynamic variation of the microscopic structure in biological tissues. The experimental results were confirmed by Monte Carlo simulations, showing that polarization imaging can effectively capture the dynamic variation in tissue microstructure, but faster speed needs to be considered when applied to living samples.

Summary: This work introduces the concept of anisotropic dielectric susceptibility matrix of anisotropic medium for both nondepolarizing and depolarizing medium, providing a new way of analyzing light scattering properties of anisotropic media illuminated by polarized light. The explicit expressions for the elements of the scattering matrix, Jones matrix, and Mueller matrix are given, which may prove stimulating for researchers working on new methods for analyzing light scattering properties.

Summary: Due to the double-pass configuration and noise in the system, the calibration of a collinear backscattering Mueller matrix imaging system is usually complex and of poor accuracy. In this work, we propose an alternative modified eigenvalue calibration method (ECM) based on the equivalent standard sample, which improves the accuracy by more than 40 times compared to other variants of the eigenvalue calibration method used in the double-pass system. The comparison results with error model-based calibration methods show that the modified eigenvalue calibration method generally provides the best accuracy, precision, and reliability.

Summary: Understanding and revealing the mechanism or sources of medium depolarization behaviors is crucial. The paper presents an interpretation method using physical generators, different rotation matrices, and their evolutions to express depolarizing differential matrix. The expression is obtained by summing up nine physical generators. Relations between generators are derived using different rotation matrices, providing new expressions with different combinations of generators. It is found that different expressions can be seen as equivalent results obtained under different generators, explaining the mechanism of depolarization effects in media. Transformations among these expressions demonstrate the uniqueness of the interpretation method and the diversity of representations, corresponding to the mechanism of depolarization behaviors and the various possibilities of causes.

Summary: Monte Carlo techniques are widely used in polarized light simulation. There are two main types of sampling strategies for scattering direction based on different preconditions: scalar sampling method and polarized sampling approaches. Efficient scattering sampling method is essential for the coupling simulation of the atmosphere and ocean in oceanic lidar polarized simulation.

Summary: Using a single scattering theory, this study derives the expression of the degree of polarization for light scattered from a layer with both surface and volume scattering. The expression reveals the close connection between the degree of polarization and the statistical correlation between surface and volume disorders, and allows for quantitative analysis of different levels of correlations. The study shows that measuring the degree of polarization can assess the surface-volume correlation function, and vice versa, the degree of polarization can be controlled through appropriate design of the correlation function.

Summary: Scattered light polarization plays a significant role as an indicator and characteristic in various atmospheric processes. By measuring the polarization of all scattering matrix elements, the optical and morphological parameters as well as the orientation of particles in clouds can be adequately described. This article focuses on the calibration of matrix polarization lidar (MPL) parameters, specifically through the calibration by air technique to correct optical element parameters.

Summary: Measurement of polarization degree of backscattering light from rough surfaces is crucial for targets-detection applications. By decomposing a realistic, complicated target as typical geometric surfaces and using a microfacet model, the polarized bidirectional reflectance distribution function (pBRDF) can be obtained to distinguish between targets at different spatial orientations.
