Abstract

Active thermography was used for characterisation of multi-layered paintings panel structures and analysis of defects caused by aging and environmental effects. Pulsed Thermography setup was applied to provide and inspect a dynamic thermal response, which was recorded by mid- and long wavelength infrared TELOPS cameras. Control, synchronization and data analyses were provided by Professional software (DisplayImg 7). Active thermography was demonstrated as being appropriate for characterization of various defects on painting layers and detection of under-drawings, pentimenti and canvas. Such multispectral approach provided simultaneous complementary information on the specimen under inspection.

Streszczenie

Aktywna termografia została wykorzystana do charakteryzacji wielowarstwowych struktur paneli malarskich i analizy defektów spowodowanych starzeniem i wpływem środowiska. Termografia impulsowa została zastosowana w celu zapewnienia i kontroli dynamicznej odpowiedzi termicznej, która była rejestrowana przez kamery TELOPS o średniej i długiej długości fali. Kontrolę, synchronizację i analizę danych zapewniało profesjonalne oprogramowanie. Aktywna termografia okazała się odpowiednia do charakteryzowania różnych defektów na warstwach malarskich i wykrywania podrysowań, pentimenti i płótna. Takie wielospektralne podejście zapewniło jednoczesne uzupełniające się informacje na temat badanej próbki.

Słowa kluczowe
