Low-energy electron beam focusing in self-organized porous alumina vacuum windows [PDF]
, 2000 Micromachined, micron-thick porous alumina membranes with closed pore endings show high electron transparency above an energy of 5 keV. This is due to the channeling of electrons along the negatively charged insulating pores after surmounting the thin ...

Digital holographic microscopy and focusing methods based on image sharpness
Journal of Microscopy, 2014 SummaryDigital holographic microscope allows imaging of opaque and transparent specimens without staining. A digitally recorded hologram must be reconstructed numerically at the actual depth of the object to obtain a focused image. We have developed a high‐resolution digital holographic microscope for imaging amplitude and phase objects with ...

Sharp focusing of linearly polarized asymmetric Bessel beam
Computer Optics, 2015 We conduct the numerical and experimental study of sharp focusing of a linearly polarized asymmetric Bessel beam with topological charge n = 3 and a crescent-shaped transverse intensity pattern. Using the Debye integral, we show that in the focal plane of a high NA aplanatic lens (NA = 0.9 – 0.95) the intensity distribution is also crescent-shaped ...
