| abstract |
An image resolution technique below the diffraction limit and other imaging techniques, including three-dimensional imaging techniques. In one aspect, the invention relates to determining and / or imaging light from two or more entities separated by a distance less than the diffraction limit of incident light. For example, these entities may be separated by a distance of less than about 1000 nm, or in the case of visible light, may be separated by a distance of less than about 300 nm. In some cases, the positions of the entities described above can be determined for all three spatial dimensions (ie, for the x, y, and z directions), and in certain cases, all three-dimensional positions. Can be determined with an accuracy of less than about 1000 nm. In one set of embodiments, the entities described above may be selectively activatable. That is, it is possible to activate a certain entity and generate light without activating another entity. [Selection figure] None |
