摘要：

Near-field scanning optical microscopy (NSOM) allows simultaneous mapping of both the topography and optical properties of a surface with resolution below the diffraction limit. Second harmonic generation (SHG) always occurs at a surface, even for centrosymmetric media, because of symmetry breaking. By combining NSOM and SHG we can study local variations in symmetry breaking, caused for example by ferroelectric and ferromagnetic domains, and can correlate them with surface topography. We report NSOM/SHG measurements made on piezoelectric ceramics, ferromagnetic materials and periodic structures.
