Virtual photonic restoration applied to cultural heritage

As time goes by, the works of art that make up a country’s cultural heritage start to degrade. Lately, the development of new restoration techniques that are capable of solving the damages caused by humidity or electromagnetic radiation, among others, seems to attract people’s attention more and more.

The Lighting and Color Group of the Complutense University of Madrid studies the development of non-invasive techniques to characterize optical parameters and so, virtually restore works of art through the use of lighting.

The study is financed by the Ministry of Science of the Spanish Government through their state RDI program called “Research Challenges 2018”.
