A High-Precision Multi-Beam Optical Measurement Method for Cylindrical Surface Profile
To automatically measure the surface profile of a cylindrical workpiece, a high-precision multi-beam optical method is proposed in this paper. First, some successive images for the cylindrical workpiece’s surface are acquired by a multi-beam angle sensor

Conversion of a conical wave with circular polarization into a vortex cylindrically polarized beam in a metal waveguide [PDF]
In this paper, we have developed a mathematical base for describing the propagation of waves in a metal waveguide in a cylindrical coordinate system. The transformation of a conical wave with circular polarization into a cylindrically polarized vortex ...

Super‐resolution optical microscopy using cylindrical vector beams
Abstract Super‐resolution optical microscopy, which gives access to finer details of objects, is highly desired for fields of nanomaterial, nanobiology, nanophotonics, etc. Many efforts, including tip optimization and illumination optimization etc., have been made in both near‐field and far‐field super‐resolution microscopy to achieve

Focus shaping using cylindrical vector beams
We report a focus shaping technique using generalized cylindrical vector beams. A generalized cylindrical vector beam can be decomposed into radially polarized and azimuthally polarized components. Such a generalized cylindrical beam can be generated from a radially polarized or an azimuthally polarized light using a two-half-wave-plate polarization ...

Enhancing the Spin Hall Effect of Cylindrically Polarized Beams
Two linked gear wheels in a micromachine can be simultaneously rotated in opposite directions by using a laser beam that has in its section areas the spin angular momentum (SAM) of the opposite sign.

Focusing a second-order cylindrical vector beam with a gradient index Mikaelian lens [PDF]
In this paper, we numerically simulate the focusing of a second-order cylindrical vector beam with a gradient index Mikaelian lens. It is shown that the lens forms a region of the reverse energy flow near its output surface.

Polar POLICRYPS diffractive structures generate cylindrical vector beams [PDF]
Local shaping of the polarization state of a light beam is appealing for a number of applications. This can be achieved by employing devices containing birefringent materials. In this article, we present one such enables converting a uniformly circularly polarized beam into a cylindrical vector beam (CVB).
