Art Imaging

The connection between biological tissue and historical artwork may seem strange at first, but the tools in our lab are excellent for performing three-dimensional imaging of both.  The key is depth.  Just as the structure of a melanoma changes as you look deeper into human skin, the structure of a painting changes as you look through the visible layer to see what lies beneath.  By coupling two different colored pulses with a variable interpulse delay we can take 3-D chemical specific images of historical art pigments.

Jointly funded by NSF Project CHE-1309017, the Center for Molecular and Biomolecular Imaging, and the North Carolina Museum of Art.
