An isopachic method with unpolarized light using a Mach-Zehnder interferometer is proposed. In the case of light, isopachics are observed not only due to change in thickness model but also induced birefringence. contrast existing methods, proposed allows you study sections three-dimensional models or flat stressed samples no variation. A brief theoretical consideration based on formalism cohere...

Thermo-deformable plastic films experience an optical birefringence phenomenon when they are subjected to mechanical strain, this phenomenon can be described by color fringes behavior observed in sequences of images acquired through photoelasticity assemblies. This paper proposes a temporary morphological analysis that color fringes experience when the plastic film is deformed. For the image an...
