  • The principle of operation of piezo-optic transducers is based on the photoelasticity effect which consists in the appearance of optical anisotropy in initially isotropic media or in a variation of optical anisotropy in anisotropic media, such as crystals, under the action of mechanical stresses occuring in the medium as a result, for example, of applying, thereto external forces.
