Hyperspectral Imaging for artwork analysis
Clyde HSI has analyzed materials and dyes on historic tapestries using hyperspectral imaging in an academic collaboration with the Historic Royal Palaces, Because this method of analysis combines standard imaging and non-invasive analytic methods, it is becoming increasingly relevant to the art sector.
For this project, a high-resolution ClydeHSI Art scanner with both a push-broom visible to very-near infrared (VNIR; 400–1000 nm) and near infrared (NIR; 900–1700 nm) hyperspectral cameras was used.
Initial testing focused on characterizing and mapping various materials used on historic tapestries.
