Pomiary krzywizny powierzchni malowidła skanerem optycznym Atos na przykładzie kopii obrazu Petera Paula Rubensa Znalezienie Erichtoniosa ze zbiorów Muzeum Narodowego w Warszawie

Ever since artists have started using wooden panels as support of their paintings it`s instability has been causing problems. Throughout centuries artists and woodworkers have been aiming to counteract the movement of the support, and as a result the cradle – a rigid wooden structure attached to the panel back was invented. For more than two centuries cradling seemed to be the perfect solution and was a customary method employed all over Europe. Today the disastrous effect of the excessive restraint the cradle exerts on the panel is apparent. It results in splitting of the panels, peeling off the paint layer and paint loss. Presented in the article are the results of measurements of surface of cradled painted panel examined by Atos – the optical scanner. The measurement was performed of the existing cradle related distortion of the surface. It demonstrated that is possible to monitor the state of deterioration of artifacts by using the optical scanner. Translated by Aleksandra Trochimowicz
