The RICH project (Reflectance Imaging for Cultural Heritage, Illuminare, in collaboration with ESAT) is developing an imaging tool for research, study, and exploration of the material characteristics of graphic materials produced in medieval and early modern times. The development of the RICH minidome enables multi-spectral imaging, expands non-destructive art-technical research and has great potential in determining conservation treatments of irreplaceable cultural heritage artifacts. With the minidome, the topography of medieval book illuminations, stamps, inks, seals and bookbinding stamps is visualized and monitored in 3D.
