  text: Confocal Raman spectroscopy was performed as an archetype imaging method to
    study the ferroelectric domain structure of periodically poled lithium niobate.
    More precisely, the linkage out of spatial resolution and spectral information
    proved itself as very useful. Here a specific modulation of the Raman lines by
    the local variation of polarity and a non-symmetric measuring-signal across the
    domain structure were found, which allows for imaging of domain boundaries as
    well as oppositely orientated domains. The high potential of this method is demonstrated
    by the visualization of the ferroelectric domain structures based on various phonon
    modes.

  text: We present results on ferroelectric micro-domains obtained by confocal second
    harmonic microscopy. The high potential of this technique is demonstrated by imaging
    periodic ferroelectric domain structures in the surface of planar X-cut lithium
    niobate (LN) and in the body of ridges fabricated by plasma etching on X-cut LN
    as well. In both cases the measured second harmonic signal reveals a strong contrast
    between inverted and non-inverted domain sections. This enabled a depth-resolved
    non-destructive tomography of micro-domains in ridge structures in all three dimensions.
