An optical instrument is said to be able to resolve two-point objects if their corresponding diffraction pattern is distinguishable.
The resolving power of an instrument is ability of the instrument to produce separate image of object which are very close to each other.

Rayleigh’s criterion of resolution:
Rayleigh’s proposed a criterion for the resolution of two close objects or spectral lines on the basis of the resultant intensity distribution curves of two close point’s objects or two close spectral lines.
This criterion is called the Rayleigh’s criterion of resolution
