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: 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: Polarization characteristics play a crucial role in various fields, but current polarimetric metrics have limited efficacy in high turbidity conditions. In this study, the use of indices of polarimetric purity (IPPs) is proposed as excellent metrics for object identification in scattering conditions. Imaging experiments on different objects under different turbidity levels demonstrate the superiority of IPPs in enhancing image contrast and improving discriminability, especially when combined with dehazing or enhancing algorithms.

Summary: This paper presents C-band Mueller matrices for the Green Bank Telescope, allowing determination of on-sky Stokes parameters for point sources at the beam center. Standard calibrators, 3C 138 and 3C 286, were observed using the Spider program, and the Mueller matrices were found to vary with frequency and calibration gain. However, by correcting for the relative calibration gain, a frequency-independent Mueller matrix can be obtained for reliable polarization measurements.

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: This study compares six popular prioritisation methods in the analytic hierarchy process. The methods are assessed based on evaluation criteria including Euclidean distance, order reversal criterion, and Manhattan distance criterion. The results show that the cosine maximisation method performs the best in terms of Euclidean distance, while most methods exhibit similar performance in terms of the order reversal criterion. The logarithmic least squares method produces priority vectors that are closer to the aggregated reference priority vector based on the conformity indicator.

Summary: Depolarization is an important contrast mechanism in biological and medical imaging. This paper presents a historical review on polarization algebra, measures of depolarization, and purity spaces, and discusses their connections with the eigenvalues of the coherency matrix. The advantages of a barycentric eigenvalue space are outlined, and a new parameter called diattenuation-corrected purity is introduced. The use of a combination of eigenvalues of coherency matrices to specify the depolarization condition is proposed. The relationships between optical and polarimetric radar formalisms are also reviewed.

Summary: This paper investigates the noise-induced depolarization effect in catheter-based polarization sensitive optical coherence tomography (PS-OCT) and proposes a method that reduces the impact of depolarization by polar decomposition and Mueller matrix averaging (MMA). Simulation and experimental results show that the polarization contrasts processed by MMA are superior to those processed by Jones matrix averaging (JMA), particularly in areas with high depolarization.

Summary: In this letter, a new design for elliptical retarders based on two quarter-wave retarders with an angle offset is presented, which is suitable for polarimetric measurements based on rotating compensator systems. This design offers the minimum condition number achieved by traditionally optimal polarimeter setups, and can further improve the accuracy of polarimetric imaging measurements in the presence of error sources, with the advantage that it only requires common quarter-wave retarders.

Summary: A complete formulation of the electromagnetic problem for light incidence from a transparent to an absorbing medium (isotropic materials) is presented. All relevant formulas that relate the polarization and Poynting vectors of the reflected and transmitted beams to the incident ones are explicitly obtained based on the standard separation in s and p polarization cases. The procedure is overall compact, being both concise and comprehensive.

Summary: This study presents a new approach using Mueller matrix polarimetry to investigate symmetry-breaking processes during crystallization. By applying this method to cooling NaClO3 solutions, the researchers demonstrate its capability to capture the entire process, including the initial and final stages as well as the intermediate steps and dynamics. This technique provides more comprehensive information and insights into the symmetry-breaking mechanisms involved in crystal formation. Overall, this study highlights the potential of Mueller matrix polarimetry for in situ statistical measurements of optical rotation and monitoring the evolution of enantiomeric excesses.

Summary: This work expands the use of spectroscopic ellipsometry to surfaces with roughness that is similar to or larger than the wavelength of the incident light. By using a custom-built spectroscopic ellipsometer and varying the angle of incidence, we were able to differentiate between the diffusely scattered and specularly reflected components. Our findings demonstrate that measuring the diffuse component at specular angles is highly beneficial for ellipsometry analysis, as its response is equivalent to that of a smooth material. This allows for accurate determination of the optical constants in materials with extremely rough surfaces. Our results have the potential to broaden the scope and utility of the spectroscopic ellipsometry technique.

Summary: This Letter demonstrates the benefits of using a complete temporal basis in polarimeters based on photoelastic modulators rather than the commonly used truncated temporal basis. The truncated basis leads to a discrete selection of Fourier harmonics for data processing. The results are numerically and experimentally illustrated for a complete Mueller-matrix-based polarimeter on four photoelastic modulators.

Summary: This study investigates the polarimetric properties of skin, skeletal muscle, connective tissue, and fat using Mueller matrix imaging. It compares their characteristics and how they change with wavelength, including during meat aging. In-vivo and ex-vivo experiments reveal wavelength-driven tissue property variations, notably significant in depolarization effects. Differences in polarimetric traits exist, with skeletal muscle's reduced retardation and fat's increased retardation over 24 h being significant findings.

Summary: Spontaneous chiral symmetry breaking is a phenomena observed in various systems, but its origin is still debated. The energy difference between intermediate states of optical enantiomers has been suggested to be the cause of symmetry breaking, but the reason behind this is unclear. By measuring the optical rotation angle of NaClO3 enantiomeric crystals during their formation, it has been found that the energy needed to induce enantiomeric excess is equal to the energy dissipated from the solid salt, supporting the proposed model of entropy production. This understanding of chiral symmetry breaking can help explain the formation of self-organised structures and have implications for advanced materials and synthetic biological tissues.

Summary: Optically anisotropic materials form through colloidal lithography were studied using SEM, confocal microscopy, and polarimetry. A hexagonal array mask made of sub-micron silica particles was created via Langmuir-Blodgett self-assembly, and the pattern was transferred onto silicon and glass substrates using ion beam etching. Gold films were then deposited onto the etched pillars to enhance optical properties. Polarimetric measurements showed that the etching directions influenced the linear birefringence and linear dichroism, with the chiroptical responses increasing with the angle of incidence.
