optical microscopy, OTF, resolution, superresolution, widefield microscopy.
Sevenfold improved axial resolution has been achieved in
three-dimensional widefield fluorescence microscopy, using
a novel interferometric technique in which the sample is
observed and/or illuminated from both sides simultaneously
using two opposing objective lenses. Separate interference
