Never ending innovations in scientific and industrial high-resolution imaging technologies often find new applications in non-destructive investigations in the field of conservation of cultural and environmental heritage, where non-destructiveness is highly valuable even in cases when the object of interest allows for extraction of microsamples. The high rise of the non-destructive methods and technologies within last century led to wide adoption of such methods in art conservation, and today we witness a number of scientific laboratories which work specifically with objects of art. Auctions and art galleries benefit from having such technologies at their disposal due to necessity of confident certification of pieces sold or being returned back.

The question of forgery countermeasures has been around for many centuries. History tells us about forgers of Middle Ages, and nothing indicates that illegal copying could not exist earlier. Perhaps, among the first ways for artworks protection was signing pieces of art by the artist. Although, such method is obviously not reliable as the signature can also be copied. Modern laboratories identify combinations of artistic materials used by one or another artist. More sophisticated approaches involve special labels with unique chemical compounds on them. Most of these approaches exhibit various flaws.

The current talk describes a novel method in illegal copying protection – namely, identification of art by those unique patterns in their structure which form in it naturally. Among such patterns are craquelure patterns, canvas structure, chemical elements distribution and many others.

The other goal is to introduce innovative complex technical solutions for security purposes, including the advanced acoustic imaging technique, UV, X-ray, infrared imaging/spectroscopy and thermo-imaging approaches that have been recently developed and successfully applied as NDT techniques in the industrial sector. We will demonstrate the most recent results in the new field of non-destructive investigation and diagnostics of cultural and environmental heritage. We strongly believe that these advanced technical approaches will secure the art collection community as a whole, and further emphasise science’s contribution to the world of cultural and historical heritage.
