  We introduce a loss compensation method to increase the resolution of
near-field imaging with a plasmonic superlens that relies on the convolution of
a high spatial frequency passband function with the object. Implementation with
incoherent light removes the need for phase information. The method is
described theoretically and numerical imaging results with artificial noise are
presented, which display enhanced resolution of a few tens of nanometers, or
around one-fifteenth of the free space wavelength. A physical implementation of
the method is designed and simulated to provide a proof-of-principle, and steps
toward experimental implementation are discussed.
