Looking beyond the perfect lens
Looking beyond the perfect lens , W H, Wee, J B, Pendry The holy grail of imaging is the ability to see through anything. From the conservation of energy, we can easily see that to see through a lossy material would require lenses with gain. The aim of this paper therefore is to propose a simple scheme by which we can construct a general perfect lens , with gainâ€"one that can restore both ...

(b) A perfect phase-contrast microscope with the point spread function (PSF) as a delta function, consisting of a source, annular aperture, first perfect lens (PL1), sample, second perfect lens (PL2), phase plate, and detector. is sufficiently high and the oversampling condition is satisfied [34].
Computational Microscopy beyond Perfect Lenses
Phase-contrast images with perfect lenses and in situ CDI reconstructions of the dynamic biological vesicles with an x-ray fluence of 3.5e6 photons/μm2. (a) The 100-nm-thick dynamic biological vesicle, consisting of 20 frames, obtained by phase-contrast microscopy with perfect lenses.
The development of coherent diffractive imaging (CDI) in 1999 that replaces the lens with coherent illumination and computational algorithms has transformed our conventional view of microscopy.
Computational microscopy beyond perfect lenses
We demonstrate that in situ coherent diffractive imaging (CDI), which leverages the coherent interference between strong and weak beams to illuminate static and dynamic structures, can serve as a highly dose-efficient imaging method. At low doses, in situ CDI can achieve higher resolution than perfect lenses with the point spread function as a delta function. Both our numerical simulations and ...
