Room-temperature spectra and excited state lifetimes of single molecules obtained with conventional, far-field optics are reported, for the first time. The sample was the same as that used in our previous near-field single molecule work, namely 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindo...
This book contains the most recent information on optical nanoscopy. Far-Field and Near-Field properties on e.m. waves are presented which illustrate how optical images can be obtained from sub-micron objects. Scanning Probe techniques and computer processing are covered here. An explanation is giv...

The minimum spot size of the probe beam in a classical interferometer is limited by far-field diffraction to about half the wavelength of the light source. Near-field optical techniques10,15,16, on the other hand, rely on the interaction between 1Mechanical Engineering Department, Northwestern ...
So far, reaction nanoscopy has been demonstrated for lin- early polarized fields at wavelengths of 720 nm [12] and 1030 nm [13,14]. In addition to the near-field, reaction nanoscopy also allows a mapping of chemical reaction yields on a nanoparticle surface with nanometer resolu- tion. ...
Analysis of practical fractional vortex beams at far field 2022, Optics and Laser Technology Citation Excerpt : For that reason and for scientific purposes, great effort has been dedicated to measuring the fractional TC. Moreover, in Refs. [3,14,15] and more recently in [16] the authors tho...
Google Glass used a different variation of the birdbath design. They were willing to accept a much smaller field of view and thus could reasonably embedded the optics in glass. It is interesting here to compare and contrast this design with the ODG one above. ...
far-field microscopic means for viewing at least a portion of the probe and at least a portion of the object; and video display means, in signal-receiving relationship to the transducive means, for displaying a two-dimensional image which relates to the amount of detected radiation at least...
The future and promise of flat optics: a personal perspective Material platforms for optical metasurfaces Metasurfaces and their applications Controlling the phase of optical nonlinearity with plasmonic metasurfaces Molding light with metasurfaces: from far-field to near-field interactions A review...
In the conventional apertureless THz imaging using near-field waves, the detector detects a strong far-field wave (an electromagnetic wave propagating in a free space) in addition to a weak near-field wave and therefore a signal-to-noise ratio decreases due to the effect of the far-field wa...
