Abstract: The present disclosure provides a system (100) and method (500) for super-resolution reconstruction of photoelastic polarization images. Polarization cameras suffer intrinsic resolution loss because a pixel grid segments across multiple polarization orientations, degrading fringe continuity and stress-field accuracy. The system (100) includes a processor (104) receiving a low-resolution polarization intensity image (102) at each polarization orientation, a reconstruction network (108) common to the polarization orientations having an extraction stage (110), an upsampling stage (112), and an output stage (114), and a memory (106) storing a parameter (106-2) that minimizes a function (202) of a first term (204) and a second term (206) using a Laplacian operator (208) and a biharmonic operator (210). Unlike conventional methods, this approach employs a single physics-consistent network, enabling reliable digital photoelasticity for experimental stress analysis.
