用相干光沿着晶体学c轴照射钽酸锂或钽酸锂晶体，同时通过透明电极施加外部电场，允许实时、原位、非破坏性地监测铁电畴图案。通过透镜的光学近场成像直接使畴壁可视化，而远场产生关于畴边界的空间取向的平均信息。
Illumination of a lithium niobate or lithium tantalate crystal along the crystallographic c axis with coherent light while simultaneously applying an external electrical field through transparent electrodes allows real-time, in situ, nondestructive monitoring of ferroelectric domain patterns. Imaging of the optical near-field through a lens directly visualizes the domain walls, whereas the far-field yields averaged information about the spatial orientation of the domain boundaries.
