Zusammenfassung: 
Noncolinear frequency doubling (NCFD) is discussed as a sensitive technique for the characterization of acentric crystals. Two methods can be applied: `Spontaneous' NCFD where light scattered at crystal imperfections is used as second fundamental beam and `induced' NCFD where the usage of a second laser beam yields three-dimensional spatial resolution. Experimental investigations of pure and VTE-treated lithium niobate and of domain boundaries in potassium niobate are presented.
