Analysis of the spectrum of illuminations in books from the 14th and 15th centuries obtained with a hyperspectral camera
Sažetak
This paper will provide insight into the application of hyperspectral camera in the analysis of illuminations found in books dating between the 14th and 15th century. Hyperspectral imaging allows the identification of various pigments and materials used in artworks. Spectral cameras analyse the reflectance of light from the surface of objects, providing insights into their composition and structure. The application of this technology in art preservation helps uncover hidden layers and details invisible to the naked eye.
Throughout history, different pigments have been used depending on the availability and technological capabilities of the era. The main challenge in pigment analysis is separating the measured reflectance to identify different components. Linear separation does not work because the mixing of materials is not linear, materials can mix almost at the atomic level. The application of hyperspectral cameras in the analysis of illuminations from books dating between the 14th and 15th century brings invaluable benefits. These technologies enable in-depth analysis of colour layers and underlying sketches, revealing the techniques and materials used in creating these works. Hyperspectral cameras allow for precise identification of pigments and materials, which is crucial for restoration and conservation.
