摘要：

A method for analyzing the phase of photoelastic fringes by polarization image analysis using the camera equipped with a pixelated microretarder array is described. Unlike the conventional phase-stepping method, this method does not require multiple images to be acquired and can analyze problems that vary from moment to moment. Therefore, this method can be applied to viscoelastic problems, crack propagation problems, and other problems involving variation with time.
