Design and fabrication of a miniaturized, integrated, high-frequency acoustical lens–transducer system
High-frequency ultrasound transducers have been developed for high-resolution imaging applications, such as nondestructive testing and medical diagnostics. Several of these devices employ miniaturized acoustical lenses to enhance the resolution of the system; however, research has been limited due to lens fabrication restrictions at or below the millimeter scale, which also increases the diffic...
متن کاملObservation of a Single-Beam Gradient Force Acoustical Trap for Elastic Particles: Acoustical Tweezers.
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 control both the position and the forces exerted on a unique particle. Forces in excess of 1 micronewton were exerted on polystyrene beads in the submillimeter range. A beam intensity less than 50 W/cm^{2} was required, ...
متن کاملTheoretical Aspects of Single-beam Multitrapping Acoustical Tweezers
1 Abstract The concept of a multitrapping acoustical tweezer based on a focused ultrasound beam is presented and theoretically investigated. The beam is described in the paraxial approximation and it is generated by a concave transducer. The resulting focused beam exerts a radiation force on a small particle that is much smaller than the incident wavelength (i.e. the so-called Rayleigh scatteri...
متن کاملAn application of holographic interferometry to acoustical holography
Holographic interferometry with a phase-modulated reference beam is applied to an acoustic holography. A very thin, flexible, optically reflective membrane, called a pellicle, is used in the liquid as an acousto-optic interface. The method involves three processes: the motion of a pellicle caused by an ultrasonic wave is recorded as an optical hologram using holographic interferometry; the opti...
متن کاملPlume outflow intrusion impact on acoustical signal fluctuations in a pre-stratified environment
Existence of outflow intrusion introduces small-scale turbulence that perturbs the vertically stratified character of the sound velocity and causes spatial and temporal fluctuations of the sound propagation. In this experimental study, we have investigated acoustic wave propagation with frequency of 50 kHz in a pre-stratified environment with intrusion of a turbulent plume while the si...
