WebAug 14, 2024 · Abstract 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 simultaneously rotated. The induced rotation of a single particle is compared to a torque balance model accounting for the acoustic response of the particle. WebMar 31, 2024 · The most efficient way to generate a vortex beam is to use a diffractive vortex phase plate, which is a unique optic that has a helical spiral staircase structure.

WebAug 31, 2024 · Ultrasound focusing is widely used in various industrial applications, such as nondestructive testing (NDT) and medical imaging. For clinical applications, high-intensity focused ultrasound (HIFU) is a specific aspect of this technology where most of the power provided by the probe is carried to a targeted zone to coagulate biological tissues. WebBasic operation of an ultrasonic transmitter and receiver pair The acoustic waves that leave the transmitter are more similar in shape to light leaving a flashlight than a laser, so spread and beam angle must be considered. As the sound waves travel farther from the transmitter, the area of detection grows laterally and vertically. eastern black-and-white colobus monkey
