Abstract

The Mueller matrix encompasses polarization information, correlated with microstructure and optical properties. However, coupling effects complicate the retrieval of anisotropy source values. To address this, we propose a novel approach of mapping the Mueller matrix onto the Poincaré sphere and introduce a set of Global-Polarization Stokes Ellipsoids (GPSE) parameters to potentially retrieve two primary anisotropic sources: cylinder scattering and birefringence. Using porcine skeletal muscle as the reference object, we establish a database of Mueller matrices and GPSE via Monte Carlo simulation and train regression models based on multi-layer perceptron (MLP). Experimental results demonstrate that GPSE achieves comparable or even better prediction performance for anisotropy numerical values compared to the Mueller matrix model, indicating that GPSE parameters effectively contain anisotropy information present in the Mueller matrix. With an intuitive expression form and sensitivity to anisotropy, GPSE holds great potential in retrieving the values of anisotropic sources in tissues.
