This can be achieved only within the intrinsic resolution capability of the imaging process for revealing such detail.](/Images/godic/202502/14/Super-resolution_example_closeup0810.png")

Super-resolution imaging (SR) is a class of techniques that enhance the resolution of an imaging system. In some SR techniques—termed optical SR—the diffraction limit of systems is transcended, while in others—geometrical SR—the resolution of digital imaging sensors is enhanced.
