A mathematical and numerical framework for ultrasonically-induced Lorentz force electrical impedance tomography

We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force. This current can ...

Non-reciprocal acoustic devices based on spatio-temporal angular-momentum modulation.

Romain Christophe Rémy Fleury

Acoustic devices that break reciprocity, for instance acoustic isolators or circulators, may find exciting applications in a variety of fields, including imaging, acoustic communication systems, and noise control. Non-reciprocal acoustic propagation has ty ...

Measurement and modeling of microlenses fabricated on single-photon avalanche diode arrays for fill factor recovery

Edoardo Charbon, Juan Mata Pavia, Martin Wolf

Single-photon avalanche diode (SPAD) imagers typically have a relatively low fil factor, i.e. a low proportion of the pixel's surface is light sensitive, due to in-pixel circuitry. We present a microlens array fabricated on a 128x128 single-photon avalanch ...
