Terahertz technology for cultural heritage testing: a Taj Mahal case study (2026-2029)
Abstract
Countless visitors to the Taj Mahal have been profoundly impressed and moved by its grandeur. Yet, today it faces an urgent threat of environmental degradation: a fate shared by many stone monuments worldwide. This study aims to advance critical knowledge supporting UNESCO and UN initiatives in preserving sites of cultural heritage. By employing cutting-edge terahertz imaging and spectroscopy, this project aims to deploy non-destructive testing methods to tackle two pressing challenges: (a) detecting surface deterioration caused by chemical, biological, and nano-scale agents, and (b) assessing structural integrity and stress issues arising from material degradation and environmental changes.
