“…OCM combines the low-coherence imaging properties of optical coherence tomography (OCT) [53] and the high spatial resolution of confocal microscopy, and unites their unique properties in order to obtain three-dimensional structural information from below the surfaces of materials. OCM allows high speed imaging with micron resolution, and was mainly improved for biological and medical sciences, but applications in the field of material characterization and non-destructive testing started to emerge, similarly to the situation for OCT [54,55]. The light sources used are typically at wavelengths in the 800-1030 nm spectral range, due to light absorption by water in biological tissue.…”

In this review, we present nonlinear optical methods, based on the second and third order nonlinear polarization, especially in the context of material characterization tasks outside the area of life sciences-for which these techniques are mostly designed. An overview of application studies reported to date is given, together with a discussion on the advantages and limits of the individual methods. Furthermore, new ways of experimentally combining different optical concepts are introduced, and their potential for characterisation and inspection tasks is evaluated in the context of various case studies, including the investigation of semiconductor surfaces, metals and related corrosion products, as well as of organic materials.
