Optics & Art: Revealing the Hidden Truth

This month’s cover story looks at how terahertz imaging is being used to analyze works of art. Other noninvasive optical scanning methods are also being used to reveal hidden layers in artworks, and to help confirm creation dates and authenticity without risk of damage. Here are a few recent examples leveraging optical coherence tomography (OCT) and macro X-ray fluorescence (MA-XRF).
