The removal of aged and deteriorated molecular overlayers from the surface paintings is a delicate critical intervention in Cultural Heritage (CH) conservation. This irreversible action gets particularly complicated given multitude materials that may be present within painted work art (often ultrathin layers or traces), as well exceptional sensitivity original surfaces to environmental conditions such heat, light, so on. Lasers hold an important role among available cleaning methodologies,...
The two-wavelength laser cleaning methodology has been introduced and developed in order to meet demanding challenges CH. innovation lies on the combined use of two beams, allowing thus control ablation effective regimes towards an efficient safe result. A series studies technical samples real fragments aimed at defining refining this ensure that original surface, including its details historic traces, will be safeguarded. In paper related research applications presented attempt enlighten...
Nowadays the use of laser technology as a highly precise tool for cleaning paintings is gaining ground. The development non-invasive analytical protocol aimed at thorough assessment treated surfaces and real time monitoring action thus becoming imperative. This ensures that no side effects (e.g. discoloration, darkening, blackening) will occur on painting due to ablation. In present study potential combined optical coherence tomography (OCT) reflection FT-IR spectroscopy in situ procedures...
Currently, removal of graffiti from stone monuments is a particularly challenging task. Lasers, being highly controllable and precise tools with minimal chemical waste, offer key solution in this respect significant amount research has been dedicated to subject. Studies related the laser cleaning carbonate stones (such as limestone marble) reported extraction layer, although damage substrate can be also detected. Recently, efforts have focused on granite, which complex due its grained...
Cultural Heritage (CH) (In the context of this paper, we consider cultural heritage built tangible heritage, such as buildings or monuments.) is an important source identity for humankind and needs to be conserved future generations. Climate change (CC) will morph environmental landscape, thus leading climate stress imposed on CH. Experts from different domains, including, but not limited to, material scientists, conservators managers collaborate find out how CC affects CH potentially...
The feasibility of laser cleaning for the removal a variety surface deposits from fragments real wall paintings monumental cemetery Pisa using Nd:YAG at 1064 nm (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>μ</mml:mi></mml:math>s), (ns), and (ps) regimes is presented. Multianalytical investigations samples irradiated surfaces were carried out in order to characterize original added materials detect any laser-induced alterations; analysis included scanning electron...
The application of laser cleaning methodologies to light-sensitive substrates such as those encountered in artistic paintings is an extremely delicate issue. and polychromes irreversibly invasive intervention; therefore, prior the implementation methodologies, a thorough characterization interaction between pulses painting components required. In this work, modifications induced by irradiation with 150 picoseconds (at 1064 213 nm) 15 nanoseconds on unvarnished aged model egg-yolk-based...
The nonlinear optical microscopy (NLM) modalities of Multi-Photon Excited Fluorescence (MPEF) and Third Harmonic Generation (THG) have been combined in this work to characterize as a function depth with micrometric resolution the type extent morphological photochemical modifications that take place upon ultraviolet (UV) pulsed laser removal dammar varnish layer applied on photosensitive substrate. latter consists synthetic polymer poly-methyl methacrylate doped photosensitizer, aromatic...
Abstract Photoacoustic (PA) imaging is a novel, rapidly expanding diagnostic technique, which has been predominately developed in the context of contemporary biomedical research studies. In this review, we demonstrate how PA technologies can break through barriers biomedicine to find innovative applications cultural heritage (CH) diagnostics and laser cleaning monitoring. Having over three orders magnitude higher transmission strongly scattering media, compared light visible near infrared,...
