Laser renovation of monuments and art works

The main aim is to design, investigate and develop laser
systems and technologies for the restoration of monuments,
and art works, environmentally-friendly methods for the
fast and precise treatment of objects.

The main aim of the project is the design, development and investigation of laser systems and technologies for the restoration of monuments and art works. Under development will be also diagnostic techniques of monuments, ancient buildings and art works, based on spectroscopic analysis of laser evaporated microparticles of investigated samples, non-destructive surface testing using low power lasers and ultrasounds as well as visual inspection of object surface structure with endoscopes (borescopes). The base of developed systems will be 'ReNoVaLaser', solid-state Nd:YAG laser system (with II, III and IV harmonics of fundamental 1.06 microns wavelength) developed in IOE MUT (main participant) as well as different sources of radiation developed in other participating research centres. Particular objectives are as follows: 1. Development of devices and techniques for the renovation of wide scale antiques depending on material (organic and inorganic) of surface/ substrate, kind, age and dimension of pollutants to be removed. 2. Development of the base of the laser and opto-electronic diagnostic for monuments, historical buildings and art works. 3. Development of integrated systems able to control the amount of ablated materials, evaluating the surface reflectivity and/ or absorption and measuring the ablation depth with an opto-electronic system (non-organic base materials). 4. Development of a database collecting the known results regarding the efficiency and limits of various laser based techniques used in artwork restoration. 5. Employment and technique development of a handheld fibre laser output source for high precision treatments of 3D-objects and a remote computer-controlled high-precision prototype laser cleaning system. The main advantages of the laser technologies for the surface renovation of priceless works are their efficiency connected with no risk of mechanical or chemical damage, environmental protection as well as selectivity in acting only on the definite parts of the objects. The ease of displacement of a laser system or laser beam is also essential. The restoration and art history expert partners will define and select samples and objects for which conventional renovation techniques appear difficult, inefficient or impossible. The laser technology and industrial partners will demonstrate all the advantages of contact-less laser cleaning and will develop new or adapt existing methods of object diagnosis and control of the laser-material interaction. Keywords: laser renovation, Nd:YAG laser, art works.
