MULTISPECTRAL ANALYSIS OF CULTURAL HERITAGE ARTEFACTS

Several methods of nondestructive optical testing of works of art are described and analysed in the contribution. Main attention is paid to analysis of near infrared reflectography, ultraviolet fluorescence method and X-ray radiography. These methods give us possibility to reveal underdrawings in paintings, older compositions of picture, hidden signatures and retouched areas of works of art without any damage of them.
