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 resolution of an optical system (like a telescope or a camera) is limited by the so-called Rayleigh criterion ... including microscopes, telescopes, and cameras. The quantitative formulation ...

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.

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 now ...
