Advanced Damage Detection though Optical sensor Network


Due to the coronavirus pandemic (Covid-19), we had to make the decision to postpone the RADOPT 2020. The conference RADOPT 2021 will take place on-site in November 2021 (15th-18th) With best regards, RADOPT 2021 Organizing Committee. Radiation Effects on optical devices –

Comparison between the UV and X-ray Photosensitivities of Hybrid TiO2-SiO2 Thin Layers

The photo-induced effects on sol–gel-based organo TiO2-SiO2 thin layers deposited by the dip-coating technique have been investigated using two very different light sources: A light-emitting diode (LED) emitting in the UV (at 365 nm, 3.4 eV) and an X-ray tube producing 40 keV mean-energy photons. The impact of adding a photo-initiator (2,2-dimethoxy-2-phenylacetophenone-DMPA) on the sol–gel photosensitivity…

Sol–Gel Waveguide-Based Sensor for Structural Health Monitoring on Large Surfaces in Aerospace Domain

The potential of sol–gel-based optical sensors is investigated for applications in the aerospace domain. To this aim, a low-cost and non-intrusive sol–gel sensor based on waveguides, arranged as a 2D matrix structure, is fabricated by UV photolithography for delamination and damage detection. Two different organic–inorganic sol–gels were selected to fabricate the photonic device: TiO2–SiO2 and ZrO2–SiO2, acting…

Multifunctional pic-based SHM equipment for Aerospace

Author: R. Evenblij, Technobis For Aerospace environments, sensor data and sensing systems are commonplace. Aircraft owners depend on those sensors, systems and signals to provide real-time structural health monitoring, supporting operational awareness and decision making, and to predict future behavior. Analysis methods in SHM more and more tend to explore monitoring approaches based on analysis…

Extreme fiber sensing capabilities for composite materials in aerospace

Author: J. Mertes, M. Haverdings, R. Evenblij, Technobis This work describes the use of a high-speed fiber optic interrogation unit based on integrated photonics in structural health monitoring. It overcomes the limitations of other high-speed interrogators with respect to dynamic range by employing a small scale demultiplexed interferometer. The interferometer is combined with another chip-based…
