The three imaging modalities of the scanner include reflectance (400 - 2500 nm, 2.5 nm sampling), molecular fluorescence (400 - 1000 nm) and X-ray fluorescence. The first two modalities provide molecular information and the third elemental information about artists’ materials (pigments and paint binders). The resulting material maps reveal insight into how artworks are constructed and modified. The type of information that can be obtained from this scanner will be presented with case studies such as Leonardo da Vinci’s Ginevra de' Benci and Pablo Picasso’s Le Gourmet, both in the collection of the National Gallery of Art, Washington DC.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
