摘要

The present study discusses the potential of an integrated application of Nomarski differential interference contrast and cathodolummescence microscopy for the investigation of building materials such as natural stone, cement, mortar and concrete. Nomarski differential interference contrast microscopy is a modem technique applied in materials sciences to visualize different phases and/or to image the surface relief on the scale of 50 ran. It is based on the principle of beam splitting by a double-crystal prism split, resulting in the superposition of laterally shifted wave fronts. In cathodolummescence microscopy, the luminescence signal is excited by an electron beam and is generated by different point defects within the material. Therefore, cathodolummescence is a powerful method to characterize the defect structure of solid materials, to distinguish different phases and to reveal detailed information about their chemical composition. By combining Nomarski differential interference contrast and cathodolummescence microscopy, textural, crystallographic and chemical information can be obtained from the same sample area in a polished thin section.
