角分辨率

$Airy diffraction patterns generated by light from two points passing through a circular aperture, such as the pupil of the eye. Points far apart (top) or meeting the Rayleigh criterion (middle) can be distinguished. Points closer than the Rayleigh criterion (bottom) are difficult to distinguish.$

$Log-log plot of aperture diameter vs angular resolution at the diffraction limit for various light wavelengths compared with various astronomical instruments. For example, the blue star shows that the Hubble Space Telescope is almost diffraction-limited in the visible spectrum at 0.1 arcsecs, whereas the red circle shows that the human eye should have a resolving power of 20 arcsecs in theory, though normally only 60 arcsecs.$

瑞利准则，或瑞利判据（Rayleigh criterion）表示了一个光学仪器的角分辨度（Angular resolution），最早由瑞利提出。

衍射限制了透镜的分辨度。透镜的口径，可以视为单狭缝的二维版本。经过狭缝的光波干涉，形成所谓的爱里衍射图样。这引致图像模糊。圆孔衍射的光强可写成：

$I( \theta ) = I_0 ( \frac{2 J_1 (k R \sin \theta ) }{k R \sin \theta} )^2$

其中 $R$ 是圆孔半径， $k = 2 \pi / \lambda$ ， $\lambda$ 是光波长。 $J_1(x)$ 是贝塞尔函数。 $J_1(x)=0$ 的最小正实数解是 $x = 3.83$ ， $I(\theta)=0$ 的最小正实数解就是

这表示了若透镜和两个对象之间的夹角少于 $\theta$ ，透镜的观察者便无法分辨出有两个对象。

空间分辨度（spatial resolution）：单镜望远镜最小能观察到的对象的直径是 $l = 1.220 \frac{f \lambda}{2 R}$ ，其中 $f$ 是焦距。
