The resolution of an optical system (like a telescope or a camera) is limited by the so-called Rayleigh criterion. An international team, led by Complutense University of Madrid, has broken this ...

Optical systems such as telescopes or cameras have been limited by a phenomenon scientist call the Rayleigh criterion, which refers to the effects light has on attempts to resolve a point in an image.

According to the widely accepted Rayleigh criterion, in order to resolve two distant point sources, their angular separation must be larger than 1.22 (the wavelength of light divided by the ...

The research suggests that a relatively simple quantum set-up could be used to extract spatial information that is traditionally limited by the so-called Rayleigh criterion—a rule dating back ...

The "Rayleigh Criterion" has stood as an inherent limitation of the field of optics ever since. Telescopes, though, only register light's "intensity" or brightness. Light has other properties that ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

A light-powered microscope has a resolution limit of around 200 nanometers—which makes observing specimens smaller or closer together than that all but impossible. Engineers at the University of ...
