Sub-surface terahertz imaging through uneven surfaces: visualizing Neolithic wall paintings in Çatalhöyük

A groundbreaking image processing technique enabled the visualization of Neolithic mural paintings obscured by uneven surfaces at Çatalhöyük, Turkey. The method, based on Gaussian beam-mode coupling, overcame limitations of traditional terahertz data analysis, allowing sub-surface imaging without disturbing the archaeological site. This advancement in pulsed terahertz imaging demonstrates its potential for non-invasive study of buried artworks in complex environments.
