摘要：
A non-contact and non-destructive photothermal beam deflection (PBD) method has been used for the characterization of the thermal properties of patinated copper samples from the roof of the Stockholm City Hall. Measurements of thermal diffusivity and layer thickness performed on both the outdoor and indoor sides of patinated samples snow a significant difference in their thermal properties. Photothermal images obtained for both sides of patinated samples have been used far the analysis of patina layer surface morphology and the microstructure of inclusions.
