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.

IN vol. lxxviii. of NATURE (May 21, 1908, p. 55) was published a note on “Secondary Waves of Light,” in which I described the diffraction effects produced by an obliquely held rectangular aperture or ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Nowadays, most studies utilizing diffraction contrast tomography, either in the lab or at the synchrotron, have concentrated on relatively low-aspect-ratio samples, usually rectangular or cylindrical ...
