The application of hyperspectral imaging in the field of cultural heritage investigation is growing rapidly. In this
study, short wavelength infrared hyperspectral imaging (960–2500 nm) has been explored as a potential non-invasive
technique for in situ mapping of corrosion products on bronze sculptures. Two corrosion products, brochantite and
antlerite, commonly found on the surfaces of outdoor bronze monuments, were considered. Their spatial distribution was
investigated on the surface of the bronze sculpture The Man with the Key by Auguste Rodin in Oslo. The results
demonstrate that hyperspectral imaging combined with image analysis algorithms can display the distribution of the two
corrosion products in different areas (unsheltered and partially sheltered) of the sculpture.
