Surpassing the lateral resolution limit by a factor of two using structured illumination microscopy.

TLDR
Lateral resolution that exceeds the classical diffraction limit by a factor of two is achieved by using spatially structured illumination in a wide‐field fluorescence microscope with strikingly increased clarity compared to both conventional and confocal microscopes.
Abstract
Lateral resolution that exceeds the classical diffraction limit by a factor of two is achieved by using spatially structured illumination in a wide-field fluorescence microscope. The sample is illuminated with a series of excitation light patterns, which cause normally inaccessible high-resolution information to be encoded into the observed image. The recorded images are linearly processed to extract the new information and produce a reconstruction with twice the normal resolution. Unlike confocal microscopy, the resolution improvement is achieved with no need to discard any of the emission light. The method produces images of strikingly increased clarity compared to both conventional and confocal microscopes.

Method of obtaining optical sectioning by using structured light in a conventional microscope

TL;DR: A simple method of obtaining optical sectioning in a conventional wide-field microscope by projecting a single-spatial-frequency grid pattern onto the object and processing images that are substantially similar to those obtained with confocal microscopes is described.

Fluorescence microscopy in three dimensions.

TL;DR: This chapter has discussed the nature of image formation in three dimensions and dealt with several means to remove contaminating out-of-focus information and developed a method for extremely rapidly and accurately producing an in-focus, high-resolution "synthetic projection" image from a thick specimen.
