Bessel functions, central to many problems in mathematical physics, provide solutions to differential equations that describe wave propagation, heat conduction and vibrations in cylindrical or ...
Bessel Beams are impossible to create, can’t be destroyed, and don’t diffract. In other words, physics has discovered yet another thing that makes no sense. Bessel beams bear the name of Friedrich ...
The inherent dispersion of laser beams limits their effectiveness in precision applications. Researchers at Chiba University, ...
Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...
An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications. Bessel beams look quite different ...
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 ...
