Advanced laser renovation of old paintings, paper, parchment and metal objects

The main aim of the presented EUREKA E!3483 EULASNET LASCAN project, signed by 20 Institutions from 9 Countries and coordinated by the Institute of Optoelectronics from Warsaw, is to construct, develop, and investigate laser systems and technologies for renovation of paintings, antique books and metal works of art. The Project's Consortium intends to accomplish it through the implementation of advanced laser cleaning heads, including generation of ultra-short pulses with high repetition frequency and tunable wavelength, laser renovation technologies and complementary technologies; artwork diagnostics methods particularly methods of "on-line" cleaning process diagnostics and control; techniques of automatic laser beam scanning for application to flat objects (2D) and for irregular surfaces (3D); methods of diagnostics for renovation of the workplace environment (eye safety and air pollution control). This paper presents current developments described by project partners as well as results of events and joint experiments conducted during the project realization.
