Super-resolution techniques

Another far-field super-resolution technique demonstrated recently is the optical superoscillatory lens by Zheludev s group in Southampton. The basic idea, which has root connection with Toraldo di Francia s proposal in 1956, is to use a carefully-designed phase-mask to modulate the beam to achieve a super-resolution spot in the far-field, through constructively and destructive interference without evanescence waves... 

In addition, a number of other super-resolution techniques and proposals exist in the literature, including structured illumination. Maxwell fisheyes, scattering lens and time-reversal imaging. More details on them can be found in an interesting magazine article written byj. Cartwright. ... 

Whereas, near-field microscopy achieves a high resolution by illuminating a nanometric area with localized light around a small probe tip, the super-resolution techniques extract nanometer-scale information from optical images captured using conventional lens-based optics. Among several super-resolution techniques that have been reported, stimulated emission depletion (STED) microscopy [43-45] and...

Super-resolution techniques can be applied to obtain a deeper insight into polymer physics. By labeling polymer chains with dye molecules, the exact positions of the labels can be determined. This allows to obtain more information about, for example, the conformation of an individual polymer chain. 

If still higher fields are desired, it is possible to use well-known, though expensive, super-conducting techniques up to 18 T, while maintaining high homogeneity. Such fields represent the state of the art for high-resolution... 

With any of the super detecting techniques available today, we cannot observe the real-time movement of single molecules in sufficient resolution because the obj ective... 

Super-resolution in chromatography is defined as the ability to detect the presence of two or more components when their mean elution tines fall within two standeurd peak widths of each other. Numerical deconvolution techniques for achieving superresolution eu e considered for the case of a single channel detector (7ZD), a multichannel detector (HS) and a two dimensional detector (video fluorometer). It is shown that the degree of ambiguity of the deconvolution decreases in going from a monochannel detector to a multicdiannel detector to a multidimensional detector. Three types of analytical situations are considered for each type of detector ... 

The classic work on pitch detection is that of Hess [202] who gives a thorough overview of all the PDA techniques just mentioned. With PDAs, the basic techniques only go so far and an important component of the algorithm is the use of many heuristic or empirically determined factors. Bagshaw [28] conducted an objective test on 6 popular techniques and claims that the time domain super resolution pitch determination algorithm [309] is the best. Other well known pitch-...

The use of a single LED source has its advantages that the microscope developed is simple, small and portable. But it also suffers from some disadvantages like poor axial resolution because of under-sampling. To overcome this pixel superresolution (SR) techniques have been followed, where a super-resolution picture is obtained from a series of low-resolution images. Each image in...
