... nanometres. Increasingly, biologists have turned to physicists for help in breaking through this “diffraction” limit.
The result has been the development in recent years of several novel techniques ...
... ability to resolve.
"There is a mismatch between nanoelectronics and nanophotonics," says Gan. "Because of the diffraction limit of light, optical circuits are now much larger than their electronic ...
... of electrostatic-based imaging is determined by the number of particle-observations rather than by the diffraction limit of light, our readouts could serve as a form of ultramicroscopy," he said. " ...
Breakthrough could allow optical measurements to beat the 'diffraction limit'
... is moved and rotated. A typical series requires approximately 150 views in all.
The individual diffraction patterns are then processed by a computer. The way the photons in the beam are redirected ...
... into tiny spots smaller than the wavelength of the photons in use. These sub-wavelength spots overcome the diffraction limit, thus allowing even the smallest details of an object to be visualized.

... and shorter light wavelengths, which dramatically increases the cost of manufacturing. Also, light has a diffraction limit restricting how small it can be focused. Currently, the minimum feature size ...
... recently developed technique uses 100 MHz sound waves, controlled by custom high-speed electronics, to diffract and frequency-shift the laser light, resulting in rapid patterning of large areas with ...
... the reference beam is shining on the detector, the interference pattern serves to "unscatter" (diffract) the wavefront and reconstruct the object's image.
Lasers, which produce coherent light (all ...
