ABSTRACT
Applications of laser beam techniques in the field of Art and Archaeology have been widely developed since a few decades. Both analytical and imaging methods, such as micro-Raman Spectroscopy, Laser Induced Breakdown Spectroscopy (LIBS), Laser Radar, Interferometry and Holography, provide useful information related to the object composition, conservation state and defects. Laser-based restoration techniques which mainly consist of surface cleaning (varnish removal from paintings, elimination of gypsum crusts from the rock materials) use either continuous wave or pulsed Q-switched laser radiations.
