Autor: Sébastien Maqueda, Julien Perchoux, Clément Tronche, José Javier Imas González, Marc Genetier, Maylis Lavayssière, Yohan Barbarin

Publikováno v: Sensors, Vol 23, Iss 7, p 3720 (2023)

In this paper, we demonstrate that a compact and inexpensive interferometric sensor based on the self-mixing effect in the laser cavity can be used for the characterization of shock waves. The sensor measures the changes in the refractive index induc

Publikováno v: Sensors, Vol 16, Iss 8, p 1233 (2016)

Optical feedback interferometry (OFI) is a compact sensing technique with recent implementation for flow measurements in microchannels. We propose implementing OFI for the analysis at the microscale of multiphase flows starting with the case of paral

Acoustic flat lensing is achieved here by tuning a phononic array to have indefinite medium behaviour in a narrow frequency spectral region along the acoustic branch. This is confirmed by the occurrence of a flat band along an unusual path in the Bri
