Warren group pioneers use of laser microscopy in art history and conservation

Duke researchers,  with collaborators from the NC Museum of Art in Raleigh and the National Gallery of Art in Washington,  DC,   demonstrate the  imaging capabilities of femtosecond pump-probe microscopy to reveal the layering structures of pigments in historically relevant paintings.  In work recently reported in PNAS the Warren group successfully used the femtosecond pump-probe microscopy technique to noninvasively image the paint pigments in a 14th century painting, The Crucifixion by Puccio Capanna. The research was also highlighted in Nature, Science and Chemical and Engineering News.
