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, ...

A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

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 ...

One of the best known properties of light is that it diffracts, bending or spreading around objects that lie in its path. A familiar example is when a collimated beam of light passes through a small ...

THE attention given, in this laboratory and elsewhere, to the effects produced by passing a beam of Röntgen radiation through crystals suggested to me that it might be of interest to examine the image ...

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 ...
