ESR5 – Athanasia Papanikolaou

Athanasia Papanikolaou

Country of Origin: Greece
Host Institution: WUT


Athanasia completed her Bachelor's from the Department of Physics in the University of Crete. Her BsC thesis topic was "Towards the understanding of the two wavelength laser cleaning in avoiding yellowing on stonework". Consequently, she completed her Master's in "Photonics and Nanoelectronics" from the Departmet of Physics in the University of Crete. Her MsC thesis topic was "Development of a photoacoustic monitoring system for the study of laser ablation processes upon the removal of encrustation from stonework".

Aspirations within projects:

Athanasia considers the CHANGE project as a great opportunity to expand my knowledge in two exciting fields of research: engineering with the focus of optical metrology and 3D data processing and the cultural heritage archiving and monitoring with the goal of preserving CH for future generations. Her main aspiration is that the results of my work will bridge these two fields of activities and will successfully fill important gaps in technical support for archiving and monitoring of 3D CH objects. Her aspiration is also to get acquainted with the best experts in these fields and to use the full opportunity of their participation in the CHANGE project and sharing their knowledge with her. The next very important point for Athanasia is to collaborate with other ESRs from different academic backgrounds and to create solid fundamentals of this cooperation for my future professional life.

More specifically on the research and technical side she would like to develop a multi-modal optical system for the measurement and monitoring of surfaces of 3D CH objects. There have been already developed several systems based on coherent and incoherent light methods but there are numerous uncovered needs. Athanasia wishes to gain deep understanding of these needs and combine them with cutting edge expertise in optical metrology and 3D/4D data processing. The multimodal system together with advanced data processing algorithms will enable the successful archiving and in situ monitoring of the artworks response in ambient environment changes or conservation treatments (i.e. removal of original layers of an object, deformations, displacements, strains (cracks/defects), colour alterations).

ESR5: Portable multimodal system for CH surface measurement and monitoring


  • Identification of optimal device configuration for different modalities (geometry, displacements, multispectral) taking into account measurement quality and time, cost of device, and applicability in different scenarios.
  • Development of device prototype with measurement functionality.
  • Validation using CH mock-ups.
  • As a proof of the system applicability, the measurements of CH objects during conservation processes and exposition to environmental changes will be performed.
