Optical coherence tomography (OCT): a review
... have been working toward an answer to this question, which is central to the development of a comprehensive theory of optical coherence tomography [3], [32]–[36]. The basic aspects of attenuation of a focused beam in tissue composed of particulate scatterers are described by the singlebackscattering ...

Selective Trapping or Rotation of Isotropic Dielectric Microparticles
... trapping stability, the rotational speed, as well as the dependence over the particle size. These additional controls could be approached through the variations in optical excitation power, number of spiral turns, and interestingly the surface roughness of the gold film. Our method is of great intere ...

High resolution, high contrast, high focal depth nonlinear beams
... Conical waves are unique and peculiar wave packets, in which the energy flow is not directed along the beam axis, as in conventional waves. In contrast, here the energy arrives laterally, i.e., from a cone-shaped surface, leading to the appearance of a very intense and localized interference peak at ...

Conformational Evolution of Elongated Polymer Solutions Tailors
... elongation of semidilute solutions demonstrate that the molecules stretch almost fully within less than 1 mm from jet start, increasing polymer axial orientation at the jet center. The nanoscale mapping of the local dichroism of individual fibers by polarized near-field optical microscopy unveils for ...
