Abstract (sommario):
Many different performance measures are used to characterize x-ray optics, sometimes resulting in radically different rankings. This makes it difficult, even for practitioners intimately involved in the field, to compare results from different optics and for different applications. To truly understand and appreciate advances in a specific type of optic – polycapillary optics – different methods of optic comparison are evaluated and their relevance explained. These methods include transmission efficiency, flux, flux density, equivalent distance, normalized gain, insertion gain, and effective ca

Abstract (sommario):
An optical fiber is a high-speed telecommunication transmission medium. Principally, an optical fiber is made of a very fine glass fiber material, which is able to transmit light waves using light reflection method on the surface of the fiber optics core. An underground installation of the fiber optics makes this device robust from external interferences. However, the fiber optic cable performance should always be checked to maintain performance during data transmission process. One way to test fiber optics cable performance is by using an Optical Time - Domain Reflectometer (OTDR) device. Thi

The analysis of fiber optics for macro bending-based slope sensors using SMF-28 single-mode optical fibers has been successfully conducted. Fiber optics were treated to silicon rubber molding and connected with laser light and power meters to measure the intensity of laser power generated. The working principle was carried out using the macrobending phenomenon on single-mode optical fibers. The intensity of laser light in fiber optic cables decreases in the event of indentation or bending of the fiber optic cable.

Abstract To detect faint signals from weakly scattering samples, high-resolution x-ray microscopy typically requires a high photon flux. This exposes samples to high radiation doses and can cause radiation damage. In this work we propose the use of annular optics in scanning microscopy as an alternative to full-aperture optics. Annular optics act as high-pass filters that produce a stronger signal from edges. Compared to regular optics with the same numerical aperture, annular optics expose the sample to less dose while producing the same signal from small sample features. Annular optics benef

Abstract (sommario):
X-ray optics have been used in X-ray analytical instruments for several years. Applications of X-ray optics have been reported in X-ray diffraction, X-ray fluorescence, and wavelength dispersive spectroscopy. X-ray optics have been used to increase the X-ray flux incident on the sample or to direct and focus emitted X-rays from a sample. We report here the use of a grazing incidence optic (GIO) as a flux-enhancing collimator for use with an energy-dispersive (ED) detector used to perform electron beam microanalysis. We found that the GIO in combination with an ED spectrometer (EDS) provides su

Abstract (sommario):
Applying fiber-optics on surface plasmon resonance (SPR) sensors is aimed at practical usability over conventional SPR sensors. Recently, field localization techniques using nanostructures or nanoparticles have been investigated on optical fibers for further sensitivity enhancement and significant target selectivity. In this review article, we explored varied recent research approaches of fiber-optics based localized surface plasmon resonance (LSPR) sensors. The article contains interesting experimental results using fiber-optic LSPR sensors for three different application categories: (1) chem

Using polycapillary X-ray optics, the intensity of the Cu Kα radiation from a Rigaku RU200 rotating-anode generator was increased remarkably compared with Supper double focusing mirrors. A crystal of a double mutant of trichosanthin diffracted beyond 1.9 Å with the application of the polycapillary optics and 2.0 Å resolution data with an overall R_{\rm sym} of 8.4% were collected, while the same crystal only diffracted to about 2.62 Å using the radiation from double focusing mirrors.

Abstract (sommario):
Concrete, a material that can be used as a building material and at the same time when mixed with light source, can enhance the beauty of a space as well as open new ways to experiment with it. The vision behind the research is to contribute with the manufacturers who are having “vision of cities that glow from within” through the use of concrete embedded with optic fiber strands. The aim of this research is to determine light transmitting properties of translucent concrete embedded with plastic fiber optics. In this experimental study, the amount of light is calculated that is able to transmi

AbstractAs a combination of fiber optics and nanotechnology, optical microfibers and nanofibers (MNFs) have been emerging as a novel platform for exploring fiber-optic technology on the micro/nanoscale. Typically, MNFs taper drawn from glass optical fibers or bulk glasses show excellent surface smoothness, high homogeneity in diameter and integrity, which bestows these tiny optical fibers with low waveguiding losses and outstanding mechanical properties. Benefitting from their wavelength- or sub-wavelength-scale transverse dimensions, waveguiding MNFs exhibit a number of interesting properties

Abstract (sommario):
We present a brief review of the use of nonlinear optics for broadband terahertz (THz) time-domain spectroscopy with femtosecond laser pulses. The generation of THz pulses is accomplished by optical rectification and coherent detection by electro-optic sampling or field-induced second-harmonic generation. The approach permits exceptional time response, as well as the possibility for multichannel detection schemes.

Abstract (sommario):
The demand for high-resolution optical systems with a compact form factor, such as augmented reality displays, sensors, and mobile cameras, requires creating new optical component architectures. Advances in the design and fabrication of freeform optics and metasurfaces make them potential solutions to address the previous needs. Here, we introduce the concept of a metaform—an optical surface that integrates the combined benefits of a freeform optic and a metasurface into a single optical component. We experimentally realized a miniature imager using a metaform mirror. The mirror is fabricated
