Multimodal Imaging Spectroscopy in Cultural Heritage Science
John K. Delaney, Kate A. Dooley and Amar Risbud National Gallery of Art, Washington, DC, USA
Various imaging spectroscopy techniques have proven valuable for addressing questions in cultural heritage. These methods help identify the materials used in old master paintings and provide insights into artists’ working methods. Most research has focused on visible and near-infrared reflectance imaging spectroscopy (400 to 2500 nm) and X-ray fluorescence imaging spectroscopy. Only recently have researchers started collecting image cubes in the mid-infrared range (2.5 to 16 mm), which offers access to rich molecular information in this part of the electromagnetic spectrum. The development of semi-automated processing algorithms tailored for image cubes from cultural heritage objects is now increasingly important. This talk will highlight successful applications and ongoing challenges, particularly in analyzing datasets from old master paintings.
Short Bio: John K. Delaney, PhD, is a senior scientist in the scientific research department at the National Gallery of Art, where he manages the Chemical Imaging Laboratory. His research involves developing multimodal imaging spectroscopic methods to address conservation and art-historical questions. Before joining the National Gallery, he was Chief Scientist and Manager of the Systems Engineering Department at the Advanced Sensor Business Unit of Goodrich SRS. He is an associate editor for the AAAS journal Science Advances and npj Heritage Science.
