Abstract: The inhomogeneous strain induced by a homogeneous external electric field (the converse flexoelectric effect) has been studied in a thin BaTiO$_{3}$ single crystal slab. The type of inhomogeneous strain (cylindrical and spherical bending) has been determined via the interference method, and its dependence on the applied filed is measured, as well. The influence of the domain structure on this effect has also been shown.

Keywords: Spontaneous Polarization, Astigmatism, Strontium Titanate, Inhomogeneous Strain, Interference Ring.
