What Experts Say

Patrick CassittiDirector of Science (from 2015 to 2025), Foundation pro Monastery of St. John, UNESCO World Heritage site“I have implemented the DHSPI system, the precursor to the future SafeRay, on the unique Carolingian wall paintings to gain clear insight into their structural condition and create knowledge-based documentation. I firmly believe this is a breakthrough in conservation with a unique impact on preventive care. It is a globally unique tool that empowers conservators to detect invisible structural defects in artworks before they become visible, enabling them to make the right decisions in time. It is a tool that literally transforms reactive restoration into preventive conservation and, as such, has a huge economic and cultural impact on the industry.”Dr Michel Menudirector of the Research Laboratory of the French Museums at the Louvre Palace (2001-2021)“SafeRay is a globally unique tool that empowers conservators to detect invisible structural defects in artworks before they become visible, enabling them to take the right decision on time. It is a tool that literally transforms reactive restoration to preventive conservation and, as such, has a huge economic impact in the industry, preserving priceless heritage.”Antonina Chaban (MSc, PhD)Research Technologist (fixed-term NRRP)
Heritage Science Group
National Institute of Optics - Italian National Research Council
(INO-CNR)“Through on-site experimentation carried out by me and my colleagues on wall paintings of outstanding world heritage value in Italy — including Giotto's medieval frescoes in the Bardi Chapel, the Renaissance paintings of the Brancacci Chapel in Florence and the Roman frescoes at the Castle of Baia near Naples — the Digital Holographic Speckle Pattern Interferometry (DHSPI) SafeRay system proved to significantly improve our diagnostic work. The system is non-invasive and provided us with the full-field information over large surface areas, allowing vulnerable zones to be clearly identified. As a result, conservators received from us solid scientific evidence to plan targeted conservation interventions with a level of confidence that was previously not possible for such historic surfaces. The wider availability of this instrumentation would be of invaluable benefit to the field of Heritage Science and beyond.”Dr Eleni KouloumpiLaboratory of Physicochemical Research
National Gallery - Alexandros Soutsos Museum, Athens“The application of SafeRay on portable paintings from the collection of the National Gallery of Greece, highlighted the necessity of structural diagnosis tools for the preservation of cultural heritage. Not only, it gave the conservators the opportunity to create reference defect maps before and after conservation treatments, but it also gave us the opportunity to discover inner tensions that would lead to future defects and therefore predict the evolution of the preservation state of the artwork under study. This tool must be in every Conservation Department of the Museums.”Rémi PetitcolFondation des Sciences du Patrimoine de France
Centre de Recherche et de Restauration des Musées de France“We have collaborated with the team behind Holometrica on several occasions, and the expertise was key in the success of our joint projects.”Prof. Christos KarydisHead of Department of Environment - Ionian University, Corfu“The SafeRay system played a fundamentally important role in our research at the wall paintings of Vatopedi Monastery at Mount Athos. As a high-precision scientific tool, it gave us the ability to map detachments and quantify stresses across large mural surfaces in an objective and repeatable way. SafeRay is not merely a diagnostic instrument; it is a foundational component of a modern, scientifically documented approach to the preventive conservation and optimal management of cultural assets.”Nikolas BakirtzisPhD. Professor and Director of the Andreas Pittas Art Characterization Laboratories (APAC Labs) at the Science and Technology in Archaeology and Culture Research Centre of the Cyprus Institute“SafeRay can significantly enhance the conservation and study of works of art. This is a highly innovative non-destructive, non-invasive tool can offer unique insights into the structural integrity and the state of preservation of a range of cultural assets, such as portable paintings, frescoes and icons. As an art historian, I was able to observe the impressive results of the SafeRay system enabling the dynamic visualization of preservation conditions. It is an invaluable tool for preventive conservation, diagnostics and the appropriate management of cultural heritage assets. At the same time, SafeRay holds great research potential as it enriches our understanding of the complex materiality of art. Heritage Science innovation at its best!”Dr. Haida LiangDistinguished Professor at Nottingham Trent University
Head of the Imaging and Sensing for Archaeology, Art history and Conservation (ISAAC) Lab“The SafeRay system is a vital asset in the structural diagnostic assessment defect documentation from small to large scale artworks (e.g. from icons to wall paintings). As a first conservation step, the system provides essential documentation of the structural condition and a comprehensive assessment of overall deformations and defect location and impact on the surface allowing prioritisation and early-stage conservation measures. Its ability to detect subsurface defects non-invasively allows to establish the precise state of condition and plan accurate intervention as well as guiding point-wise techniques. It is an indispensable tool for high-level heritage diagnostics.”Corinna Koch DandoloScientific Collaborator - Research, Development and Knowledge Transfer
University of Applied Sciences and Arts of Southern Switzerland
SUPSI University of experience“The SafeRay system was a vital asset during our diagnostic work at MASI (Palazzo Reali) in Lugano for the Renaissance panel painting 'Assumption and Coronation of the Virgin' by Bernardino Luini. The investigation work has been an initiative of the "Ufficio dei beni culturali (UBC)" of "Cantone Ticino".

Benaki Museum, Athens“The implementation of the Digital Holographic Speckle Pattern Interferometry (DHSPI) based SafeRay on portable icons from the collection of the Benaki Museum underscored the essential role of advanced structural diagnostic methodologies in cultural heritage conservation. The technique enabled the documentation and mapping of subsurface defects before and after conservation treatment, assisting the assessment and prediction of the long-term structural stability and conservation state of the examined artworks.”Valentina Di SarnoResearch Scientist
National Institute of Optics (INO), CNR - Italian National Research Council“In our experience at Baia’s Castle, SafeRay proved to be uniquely effective in detecting subsurface detachments and early-stage mechanical instabilities that are otherwise difficult to identify. Its contribution is not ancillary, but structurally decisive, particularly in a preventive diagnostics framework. Moreover, with the ongoing development toward automation and AI-assisted analysis, SafeRay has the potential to evolve into a robust, scalable, and operational technique, reducing dependence on expert interpretation and enabling wider adoption in routine conservation practice.”

Industries

Protecting What Matters Most

SafeRay serves sectors where failure is catastrophic, assets are irreplaceable, and precision is non-negotiable.

Cultural Heritage & MuseumsDetect structural degradation years before visible damage. Non-invasive monitoring protects fragile surfaces while predictive analytics optimize conservation budgets, prioritizing interventions by quantified risk.

Aerospace Manufacturing & MRODetect micro-delaminations years before traditional methods. Full-field inspection slashes labor time while predictive analytics extend component lifespans, deferring massive replacement costs.

Energy InfrastructureDetect blade delaminations and structural defects years earlier. Portable operation eliminates costly rope access. Predictive analytics optimize maintenance schedules, dramatically reducing unplanned downtime.
