TLDR
In this paper, a new type high resolution electron microscopic observation, DIMP-EM under hollow-cone illumination, has been presented, where the spherical-aberration-free complex wavefield at the exit surface of the specimen has been retrieved with the resolution 1.8 times higher than under axial illumination.

Theoretical background of defocus image modulation processing (DIMP) based on three dimensional optical transfer functions (3D-OTFs)

TL;DR: In this paper, the theoretical background of DIMP is investigated by using 3D-OTFs in 3D Fourier space under coherent illumination and the filtering characteristics of the dIMP are interpreted using the 3DOTFs.
