Angular resolution

-

Angular resolution - describes the resolution of any device that creates an image, such as an optical telescope, a telescope, a microscope, a camera lens, or a human eye. More specifically, it is the ability of such an instrument to distinguish the angular separation of the points of the object being viewed. Resolution alone means that in science the precision with which the instrument measures and records data about the sample being tested.

The resolution of the optical lens is ultimately limited by the phenomenon of diffraction. This boundary is expressed by the so-called. Rayleigh's criterion discovered by Lord Rayleigh: without ⁡ θ = 1 , 220 & # x03BB; D {\displaystyle \sin \theta =1,220{\frac {\lambda }{D}}}

where: θ {\displaystyle \theta } - resolution, & # x03BB; {\displaystyle \lambda } - wavelength of light, D {\displaystyle D} - the diameter of the lens aperture.
