Orbital angular momentum transfer to stably trapped elastic particles in acoustical vortex beams
Diego Baresch, Régis Marchiano, Jean-Louis Thomas
The controlled rotation of solid particles trapped in a liquid by an ultrasonic vortex beam is observed. Single polystyrene beads, or clusters, can be trapped against gravity while…
Design and implementation of a multi-octave-band audio camera for realtime diagnosis
Charles Vanwynsberghe, Régis Marchiano, François Ollivier +3
Noise pollution investigation takes advantage of two common methods of diagnosis: measurement using a Sound Level Meter and acoustical imaging. The former enables a detailed analys…
A robust and passive method for geometric calibration of large arrays
Charles Vanwynsberghe, Pascal Challande, Jacques Marchal +2
This paper presents a complete strategy for the geometry estimation of large microphone arrays of arbitrary shape. Largeness is intended here in both number of microphones (hundred…
Observation of a single-beam gradient force acoustical trap for elastic particles: acoustical tweezers
Diego Baresch, Jean-Louis Thomas, Régis Marchiano
We demonstrate the trapping of elastic particles by the large gradient force of a single acoustical beam in three dimensions. Acoustical tweezers can push, pull and accurately cont…
