Confocal microscopy offers several advantages over conventional optical microscopy, including controllable depth of field, the elimination of image degrading outoffocus information, and the ability to collect serial optical sections from thick specimens. The leaf picture at the start of the article was taken using a specialized kind of fluorescence microscopy called confocal microscopy. The technique features attractive advantages over confocal microscopy for imaging living cells and tissues with threedimensionally resolved fluorescence imaging. The principle of a confocal is that an aperture pinhole is placed in the image plane, so most of the outoffocus light orange in figure will not reach the detector.
The fundamental principle behind stochastic optical reconstruction microscopy storm and related methodology is that the activated state of a photoswitchable molecule must lead to the consecutive emission of sufficient photons to enable precise localization before it enters a dark state or becomes deactivated by photobleaching.
