The Multispectral Analysis on Oetzi by Profilocolore

Profilocolore collects the results of an important analysis and study work carried out on the Oetzi mummy, a project involving researchers from the Institute for Mummies and the Iceman of the European Academy of Bolzano (Eurac) Marco Samadelli, Eduard Vigl, and Albert R. Zink and the engineers of Profilocolore, Marcello Melis and Matteo Miccoli, in the multispectral analysis of the body of the Oetzi mummy.

The study was conducted using the non-invasive HMI (Hypercolorimetric Multispectral Imaging) system, developed entirely by Profilocolore, which is also used in the field of restoration and conservation of cultural heritage, in crime scene analyzes and in non-invasive dermatological diagnoses. The system is able to detect the spectral reflectance in imaging mode, thus being able to characterize and identify in an extremely detailed way the surfaces in question. An initial phase of photographic shooting from the UV to the IR, performed with a Nikon D800FR camera, modified by Nital on a Profilocolore project, is followed by a phase of calibration of the data and a recording of the images to obtain a real system of spectral measurement at a distance pixel by pixel.

Profilocolore has developed a dedicated software, the HMI-Viewer, which, starting from spectral data, performs sophisticated processing to extract the maximum information from the acquired data and manages a database of spectral signatures.


The results of the study were published by Elsevier’s Journal of CulturalHeritage with the article “Complete mapping of the tattoos of the 5300-year-old Tyrolean Iceman” which is having great resonance in the international scientific environment.
