摘要
A Mueller matrix covers all the polarization information of the measured sample,however the combination of its 16 elements is sometimes not intuitive enough to describe and identify the key characteristics of polarization changes.Within the Poincarésphere system,this study achieves a spatial representation of the Mueller matrix:the Global-Polarization Stokes Ellipsoid(GPSE).With the help of Monte Carlo simulations combined with anisotropic tissue models,three basic characteristic parameters of GPSE are proposed and explained,where the V parameter represents polarization maintenance ability,and the E and D†parameters represent the degree of anisotropy.Furthermore,based on GPSE system,a dynamic analysis of skeletal muscle dehydration process demonstrates the monitoring efect of GPSE from an application perspective,while confrming its robustness and accuracy.
