A Co-simulation Method of Polarization Imaging for Temporary Birefringent Materials

A method to simulate the polarization parameter imaging process of microstructure mechanical behavior under a coupling load of a multi-physical field is proposed. It aims to optimize the experimental process and reduce the experimental time and cost. The mechanical behavior of the quartz glass sheet in the coupling field is simulated by the finite element method (FEM). The light intensity distribution image of the loaded quartz glass sheet in the polarized light field is calculated by the numerical computation method (NCM). We obtained the results of the light intensity distribution in different degrees of polarization and the results of polarization parameter after Stokes parameter processing by combining FEM and NCM. The results show that the co-simulation method can well reflect the internal stress distribution of the loaded quartz glass sheet, which is of great significance for the follow-up guidance of the actual experiment.
