Near-field scanning optical microscopy.

TL;DR: In this paper, a simple aperture for terahertz near-field imaging at 1.43 millimeters was proposed, which is able to achieve a spatial resolution of lambda/7.

TL;DR: In this article, it was shown that lateral resolution was limited by the diffraction limit of the wavelength of the light in use, which was later improved to about half a μm.

TL;DR: In this article, an in-fiber whitelight interferometric distance sensor based on the mode coupling effect of a Long Period Fiber Grating (LPFG) for absolute distance measurement has been investigated.

TL;DR: The near-field optical interaction between a sharp probe and a sample of interest can be exploited to image, spectroscopically probe, or modify surfaces at a resolution inaccessible by traditional far-field techniques, resulting in a technique of considerable versatility.

TL;DR: A near-field probe has been developed that yields a resolution of ∼12 nm (∼λ/43) and signals ∼104- to 106-fold larger than those reported previously and image contrast is demonstrated to be highly polarization dependent.

TL;DR: In this article, the authors proposed a method for optical trapping and alignment of dielectric particles in aqueous environments at the nanometer scale based on the highly enhanced electric field close to a laser-illuminated metal tip and the strong mechanical forces and torque associated with these fields.

TL;DR: In this article, a method for extending microscopic resolution into the ultra-microscopic region was proposed, based on a method proposed by the London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science.
