• Sommario/riassunto: This Open Access book discusses an extension to low-coherence interferometry by dispersion-encoding. The approach is theoretically designed and implemented for applications such as surface profilometry, polymeric cross-linking estimation and the determination of thin-film layer thicknesses. During a characterization, it was shown that an axial measurement range of 79.91 µm with an axial resolution of 0.1 nm is achievable. Simultaneously, profiles of up to 1.5 mm in length were obtained in a scan-free manner. This marked a significant improvement in relation to the state-of-the-art in terms of dynamic range. Also, the axial and lateral measurement range were decoupled partially while functional parameters such as surface roughness were estimated. The characterization of the degree of polymeric cross-linking was performed as a function of the refractive index. It was acquired in a spatially-resolved manner with a resolution of 3.36 x 10-5. This was achieved by the development of a novel mathematical analysis approach.

• Sommario/riassunto: Die »Ordinary Language-Philosophie«, nach der die klassischen Probleme der theoretischen Philosophie nicht substanzieller, sondern begrifflicher Natur sind, gilt heute in weiten Teilen der analytischen Philosophie als überholt. Zu Unrecht, wie Nicole Rathgeb argumentiert. Sie verteidigt sie gegen Paul Grice, eine Reihe von zeitgenössischen Autoren und Vertreterinnen und Vertreter der Experimentellen Philosophie. Dabei geht es insbesondere darum, Argumente gegen die Existenz begrifflicher Wahrheiten zu entkräften, zu zeigen, wie wir auf der Grundlage unserer Sprachkompetenz nicht-triviale Erkenntnisse gewinnen können, und dafür zu argumentieren, dass wir in der Philosophie nicht auf Umfragen oder andere empirische Studien zurückgreifen müssen.
