Periodic Reporting for period 1 - iPhotoCult (Intelligent Advanced Photonics Tools for Remote and/or on-site Monitoring of Cultural Heritage Monuments and Artefacts)
Berichtszeitraum: 2024-06-01 bis 2025-07-31
develop a comprehensive, cost-effective, and scalable solution that can be deployed across Europe and beyond.
From a technical standpoint, progress achieved to date includes:
Testing of laboratory prototypes
Development and optimization of dedicated systems
Identification of the range of applications and material types suitable for analysis with the iPhotoCult tools
Demonstration of the proof of concept of iPhotoCult tools
Determination of the design of the prototypes / transportable systems
A total of 19 Use Cases have been identified, each one characterized by specific problems, conservation needs and requirements, that necessitate material characterisation and structural diagnostics both at the surface and in-depth. The tools under development within iPhotoCult aim to address the questions raised by conservation professionals and provide added value to existing analytical and diagnostic techniques. In this context, a comprehensive literature survey was conducted to assess the state-of-the-art of current methods and to identify the most appropriate KPIs.
The iSSP platform has progressed through the architecture and requirement specification phase for all diagnostic tools it will host. A demonstration prototype based on currently available data has been created to serve as a reference for integrating all iPhotoCult tools as soon as their data become available. Simultaneously, AI components are under active development. The remote monitoring bridge infrastructure has been designed with robust communication protocols and hardware specifications, incorporating miniSEED format and ringserver technology for efficient time-series data streaming. This architecture ensures seamless integration of diverse data outputs from all available tools.
Project management, as well as communication and dissemination activities have been successfully established and are progressing according to the GA. Progress monitoring is being conducted through regular project-wide and WP-level meetings.
Expanding the capacity of surface chemical diagnostics in terms of spatial resolution and accuracy by delivering a compact, multi-analytical hybrid tool incorporating a variety of photonic techniques based on Vis, NIR-SWIR, LIF, LIBS, and Raman spectroscopy, set on a tower platform for addressing the dual need for proximal sensing and remote control, encountered when monitoring built heritage, large monuments, or mural paintings, which are difficult to access.
Enabling capabilities for in-depth chemical diagnostics on-site by utilizing Photoacoustic spectroscopy for the first time, opening the capability for obtaining chemical fingerprints for a wide range of materials at unprecedented depths, which can exceed 500μm in opaque media. Furthermore, integrating PA spectroscopy with Non-Linear Optical Microscopy measurements (NLOM) in a single instrument will provide complementary chemical information which is crucial for the study of degradation effects of CH materials.
Enhancing the predictive power for in-depth evolution of structural defects in CH objects by fusing interferometric and thermographic data obtained by a novel tool combining DHSPI with IR thermography.
Customizing optical fiber point sensors for sensitive and multi-functional monitoring of temperature, humidity, strain and impact, utilizing small size, 3D printed transduction architectures attached onto CH objects, that are at high risk (e.g. during transportation), by combining new photonic and material technologies such as those of multi-core optical fibers and micro-metric polymer based porous resonators.
Innovating the data management and visualization associated with the documentation of diagnostic monitoring, conservation, and preservation processes by means of a cloud-based solution dedicated to CH conservators, professionals, and scientists, which will be an asset management platform where analytical maps will be displayed as superimposed layers ready to be explored in 2D and 3D.
