They are the first to use the specific combination -- which they termed "macroscale multimodal chemical imaging" -- to examine an ancient work of art. The new technique enabled them to learn about the raw materials the artist used, and the order in which they were applied to the painting, and it uncovered insights about the painting's connections to other work from the same era.
The approach, which is described in a paper published in Scientific Reports, integrates three existing techniques -- hyperspectral diffuse reflectance, luminescence and X-ray fluorescence -- to examine the painting.
