Rayleigh's curse limits the minimum distance that can be distinguished with visible light: on the order of 0.1 micrometer (a bacterium, for example, has a size of 2 micrometers), "which is a great ...

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 ...

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 ...
