Design of Acoustical Bessel-Like Beam Formation by a Pupil Masked Soret Zone Plate Lens
The image performance of acoustic and ultrasound sensors depends on several fundamental parameters such as depth of focus or lateral resolution. There are currently two different types of acoustic diffractive lenses: those that form a diffraction-limited spot with a shallow depth of focus (zone plat...
