Investigating the Temporal Evolution of the Deformation of Viscous Materials Utilizing Their Birefringence

In the paper, we analyze the relationship between mechanical deformation and optical birefringence to investigate the possibilities of using birefringence to study the temporal evolution of the deformation of viscous materials. Understanding the connection between the temporal evolution of birefringence and deformation can lead to the development of methods to investigate viscous processes, diffusions, and slow deformations in viscous materials. It also enables the creation of practical non-contact optical deformation, tension/pressure sensors as well as chemical sensors.
