Ultrasonic testing of steel tubes by supercritical parametric wave phase conjugation

Andrey Brysev, Leonid Krutyansky, Olivier Bou Matar, Vladimir Preobrazhensky, Philippe Pernod

An application of principles of parametric wave phase conjugation (WPC) of ultrasound to inspection of metallic cylindrical tubes including various volume densities and sizes of scattering defects is demonstrated experimentally. The magnetoacoustic phase conjugator under supercritical…

Signal processing for damage detection using two different array transducers

Faysal El Youbi, Sébastien Grondel, Jamal Assaad

This work describes an investigation into the development of a new health monitoring system for aeronautical applications. The health monitoring system is based on the emission and reception of Lamb waves by multi-element piezoelectric transducers (i.e., arrays) bonded to the structure. The emitter…

Characterization and fabrication of InGaAsP/InP deep-etched micro-waveguides

Arnaud Beaurain, Samuel Dupont, Hongwu Li, Jean-Pierre Vilcot, Christiane Legrand, Joseph Harari, Monique Constant, Didier Decoster

InGaAsP/InP micro-waveguides are fabricated by a deep (>3 μm) Reactive Ion Etching. The devices losses are measured by the Fabry–Perot technique for guide width contained between 10 μm and 0.5 μm. The measured losses range from 2 dB/mm to 14 dB/mm.
