摘要：

The paper presents a technique suitable for the determination of linear electro-optic effect (LECE) tensor components in crystal materials of any symmetry. The method is based oil the Michelson interferometer, where the sample being studied is set into one of its arms to measure the electro-induced changes of the optical path. We describe in detail the sample geometries that are needed to determine a complete set of the LECE tensor components and derive the corresponding equations. The experimental technique has been tested and verified oil lithium niobate crystals as well as applied to MgO-doped LiNbO3 crystals to study their electro-optic properties. The developed method can be useful for optical engineering, which deals with new materials being used in design or production of devices, such as, e.g., modulators or deflectors.
