We show a method for measuring small deformations of solids using the principle of the Max-Zender interferometer. In the interference pattern, we find an analytical expression for the dependence of the maximum displacement of the displacement, i.e., the change in the order of interference, on the deformation force of the solid. We will show you how to determine the Joung modulus for a solid body using specific expressions. The proposed method shows that the measurement accuracy of the deformation of solids is about 10-5 m. We describe the analytical expressions obtained for the interference order in two- and three-dimensional graphical form.
