The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

Fig. 1 | (a) The sketch of the PDSM-241. (b) Actuator layout (clear aperture: 270mm). (c) The self-corrected aberration of PDSM-241. A new publication from Opto-Electronic Advances, ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

Sieve analysis continues to be the traditional and most widely used technique for particle size determination. A sieve stack contains a number of sieves with increasing aperture size stacked upon each ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

M. G. FOUSSERAU describes, in the Journal de Physique for October, a simple apparatus for viewing diffraction and interference phenomena, a modified form of which I have experimented on with success.

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

The problem of the diffraction of electromagnetic waves by a circular aperture in an infinitely conducting planar screen is studied. Attention is focused chiefly on the low frequency end of the ...

A laser beam is shone onto a variable rectangular aperture. The size of the hole determines the type of diffraction produces on the screen. Very small apertures produce Fraunhofer diffraction, and ...
