Nondestructive evaluation of delamination cracks in textile composites by using 3-dimensional reconstruction from acoustical imaging

Wei-Jiang Xu, Yao Xu, Sylvain Treutenaere, Franck Lauro

An acoustical imaging technique performing 3-dimentional (3D) reconstruction and visualization of materials was developed and used to evaluate delamination cracks in textile composites. The method is based on 2-dimentional (2D) mechanical scan combined with ultrasonic A-scan to obtain 3D volumetric...

Development of high-speed, patch-antenna intersubband photodetectors at 10.3um

Q. Lin, M Hakl, S Pirotta, R. Colombelli, W. Wan, H Li, J. Cao, Jean-Francois Lampin, Emilien Peytavit, S Barbieri

We present our work towards the development of high-speed, GaAs-AlGaAs multi-quantum wells photodetectors at 10.3m, based on two-dimensional arrays of patch-antenna resonators. First, the results of FDTD simulations will be presented that allowed to optimize the patch array geometry and fabricate...

An Integrated Photoacoustic Terahertz Gas Sensor

Mattias Verstuyft, Elias Akiki, Benjamin Walter, Marc Faucher, Mathias Vanwolleghem, Bart Kuyken

An on-chip gas detector that transduces absorbed terahertz light to a mechanical motion using photoacoustics is proposed. The silicon chip confines light in an optical cavity, wherein an acousto-mechanical cavity is housed. The concentration of a trace gas can be determined from the amplitude of a...

Reservoir Computing for Sensing - an Experimental Approach

Dawid Przyczyna, Sébastien Pecqueur, Dominique Vuillaume, Konrad Szacilowski

The increasing popularity of machine learning solutions puts increasing restrictions on this field if it is to penetrate more aspects of life. In particular, energy efficiency and speed of operation is crucial, inter alia in portable medical devices. The Reservoir Computing (RC) paradigm poses as a...

Terahertz radiation confinement using metallic resonators

T. Hannotte, M. Lavancier, S. Mitryukovskiy, Jean-Francois Lampin, Romain Peretti

We designed, fabricated and characterized a micro-resonator in the terahertz range to increase light matter interaction using near-field optics. The goal of our device is to confine a THz electric field in a volume smaller than the diffraction limit to enhance light matter interaction with...

Broadband terahertz heterodyne spectrometer exploiting synchrotron radiation at sub-megahertz resolution

O. Pirali, Z. Buchanan, Sophie Eliet, M.-A. Martin-Mel, J. Turut, Francis Hindle, P. Roy, Jean-Francois Lampin, Gaël Mouret

A new spectrometer on the AILES beamline of the SOLEIL synchrotron facility to achieve sub-MHz resolution in the THz and far-IR regions is currently being developed. Thanks to a dedicated heterodyne detection by use of a new kind of molecular laser as local oscillator along with a Fast Fourier...
