We report zero-th and high-order acoustic Bessel beams with broad depth-of-field generated using acoustic holograms. While the transverse field distribution of Bessel beams generated using traditional ...

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

(Phys.org)—David Ruffner and David Grier of New York University have developed a technique for using Bessel beams to draw a particle toward a source. In their paper published in Physical Review ...

Tunable Bessel beam two-photon fluorescence microscopy enables high-speed volumetric intravital imaging of subcellular dynamics within living mouse brains with fully tunable spatial resolution and ...

THE worthy completion of a long and arduous task will always draw from the beholder the tribute of an almost personal gratification. Our sympathy and interest are at once enlisted by the opening ...

SEM is a common microscopy technique for scanning a surface. In SEM, a beam of high-energy electrons is fired from an electron gun towards a sample of interest. The beam of electrons is controlled by ...
