🔬 Multitel at FLAIR 2026 – International Conference on Field Laser Applications in Industry and Research Dr Yosri Haddad, researcher in the Applied Photonics Department at Multitel, will participate in FLAIR 2026: the International Conference on Field Laser Applications in Industry and Research, taking place from September 7–11, 2026, in Aix-les-Bains, France. FLAIR brings together an international scientific community working at the forefront of laser technologies, photonics, spectroscopy, and advanced sensing. The 2026 edition will feature invited speakers from leading international institutions, including #NASALangleyResearchCenter (USA), NASA’s original research center with major activities in aeronautics and space technology, as well as #ETHZürich (Switzerland), #TechnicalUniversityofMunich (Germany), #EindhovenUniversityofTechnology (Netherlands), #UniversityofScienceandTechnologyofChina (China), #AcademiaSinica (Taiwan), and other renowned research institutions across Europe, Asia, and the United States. 🎯 Dr. Haddad will present Multitel’s latest developments in Distributed Acoustic Sensing (DAS), carried out within the Interreg France–Wallonie–Vlaanderen SALOME project, with the contribution: “Nanostrain-Level Distributed Strain Reconstruction in the Sub-Hz and Few-Hz Regime Using Coherent Φ-OTDR with I/Q Demodulation”. Building on our previous developments in low-frequency distributed vibration sensing, this work takes a further step toward quantitative distributed strain measurement. Using coherent Φ-OTDR with I/Q demodulation, the approach enables dynamic strain reconstruction at the nanostrain level over more than 2 km of standard optical fiber, in the sub-Hz and few-Hz mechanical vibration regimes. This demonstrates the potential of optical fiber not only to detect low-frequency mechanical disturbances, but also to quantitatively reconstruct extremely small dynamic strains over kilometer-scale sensing distances. These developments open promising perspectives for monitoring slow mechanical dynamics in large-scale and critical infrastructures, including wind turbines, nuclear facilities, civil engineering structures, military and defense infrastructures, as well as aerospace and space systems. Participation in FLAIR 2026 provides an opportunity to showcase Multitel’s expertise in applied photonics and distributed fiber-optic sensing within a high-level international scientific community, while highlighting the technological developments achieved within the SALOME project. #InterregFWVL #Photonics #FiberOpticSensing #DistributedAcousticSensing #DAS #PhiOTDR #StructuralHealthMonitoring
