Mitra AlmasianBeside exhibiting and conserving Dutch culture heritage, Rijksmuseum also carries out an extensive research program. Currently, a large-scale research and conservation project is under way, in which Rembrandt’s Night Watch is examined using state-of-the-art techniques to uncover its structural and chemical composition.

One of these imaging techniques is Optical Coherence Tomography (OCT). This contactless technique is conventionally used in medical research to image biological tissues. OCT allows a look inside the material by constructing high-resolution 3D images of semi-transparent materials using near-infrared light. Within Operation Night Watch, Rijksmuseum and Amsterdam UMC collaborate to employ OCT for revealing the internal structure of varnish layers and the surface of the paint layer. This visualization of old and more recent varnish layers is unique and informative for the conservation phase of the Night Watch.
