Creation of a needle of longitudinally polarized light in vacuum using binary optics
Haifeng Wang,Luping Shi,Boris Luk'yanchuk,Colin J. R. Sheppard,Chong Tow Chong,Chong Tow Chong +5 more
TL;DR: In this article, a high-numerical-aperture lens is used to achieve light with longitudinal polarization, which has some intriguing possibilities for particle acceleration. But it is difficult to obtain longitudinal polarization.

TL;DR: In this article, the authors show that the very properties that have established collagen as the leading natural biomaterial are lost when it is electro-spun into nano-fibres out of fluoroalcohols such as 1, 1,1,3, 3,3-hexafluoro-2-propanol or 2,2,2-trifluoroethanol.
Journal ArticleDOI
Image Formation in the Scanning Microscope
TL;DR: In this paper, the effect of various arrangements using lenses with annular pupil functions is discussed, and it is found that Type 2 microscopes have improved imaging properties over conventional microscopes and that these may be further improved by use of one or two lenses with ANNular pupils.
Journal ArticleDOI
Annular Pupils, Radial Polarization, and Superresolution
TL;DR: An annular pupil, which can be used to produce a Bessel beam, when combined with radially polarized illumination promises improvements in microscope resolution, increased packing density for optical storage, and finer optical lithography.
