Superresolution in far-field imaging.
Based on the idea of the complex filters suggested by Toraldo di Francia in 1952 [Nuovo Cimento Suppl. 9, 426 (1952)], superresolved imaging has been achieved by use of interferometric image multiplication. A resolution limit of 55% of the Sparrow limit was achieved for incoherent objects.
