They explain how two opposing lenses, combined with the switching (on and off) of fluorescence between adjacent markers, can overcome the diffraction barrier. Although the examples given are ...

The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

IN 1924, Prince Louis de Broglie put forward the thesis that all material particles, and in particular electrons, have properties analogous to those of a train of waves. This view, which is now ...

Captured here is a laser diffraction pattern, visible as a series of concentric circles with a bright central area. This pattern is a result of light waves spreading out and overlapping after passing ...

Each image was processed and projected, and the 0.5 μμm wavelength was selected to detect the wave packets. Images A, B, D, F, and G are at Ls≈150°; Image C at Ls≈285°; Image E at Ls≈245 ...
