Fiber whispering gallery modes (WGMs) are surface waves that propagate azimuthally along the outer surface of the fiber cladding. Those waves that are in phase every turn give rise to narrow resonances defined by the resonant wavelength and a high Q factor. The actual values of the resonant wavelengths depend on the radius and the refractive index of the fiber cladding, enabling the development of several fiber characterization techniques. In addition, the typical high Q factor of these resonances (Q > 106) provides the characterization techniques with a low detection limit. Here, we report the development of a technique for measuring temperature profiles along the optical fiber, which enables the characterization of UV-induced absorption loss in photosensitive fibers, and a technique for the measurement of the elasto-optic coefficients and the anisotropy generated by the axial strain in standard fibers.

The image of human fluorescently labeled tissues is taken as short view of the subject. These images are in RGB format. We must highlight areas of interest. In this case we use the ideology of wavelets. It allows us to find a lot of points of the brightness change in the original image. We get additional information, as well as decompose the input image into separate color spaces. This allows us to specify the areas of interest for the original image. The advantage of the original image decomposition into separate color spaces is clearly shown in comparison with the image in the RGB format. The results are received by using the real images.

Application of Monte Carlo technique for optimization of wearable photoplethysmography (PPG) pulse rate sensors is suggested. The paper describes a numerical method of effective response estimation of PPG sensors taking into account penetration depth of radiation into multilayered tissue structure. The principle and photon propagation rules, which are needed for simulation are described. PPG sensor structure with 7 layer tissue parameters are presented. We show, that using the simulation results in designing the PPG pulse rate sensor optical part will enhance the level of useful received signal by the photodiode.

The subject of research in this article was the uncertainty of measuring the weight of the human body impacted to physical activity. Nordic walking was chosen as a source of physical activity. The relevance of this topic is confirmed by the statistical data of the Institute for Health Measurement and Assessment (IHME) at the University of Washington (USA), the World Health Organization and the Rosstat of the Russian Federation. The quantitative characteristic of assessing the accuracy of measurement results was selected uncertainty as an internationally recognized measure of confidence in the measurement results. In accordance with the Guidance on the expression of uncertainty (GUM) [the average arithmetic value of the mass of the object of research was determined, the standard uncertainty was calculated by type A and type B, the total standard uncertainty and the expanded uncertainty were determined]. At the end of the research, the result is the measurement of the mass of the object of study, taking into account the uncertainty, and an uncertainty budget was drawn up.

Structural, optical, and magnetic properties of the zinc-cobalt oxide (ZnCoO) thin layers obtained by a pulsed laser deposition process, grown on silicon, sapphire, glass, and quartz substrates have been investigated. The material was characterized by electron magnetic resonance, X-ray diffraction, optical transmission and absorption spectra, and conductivity measurements. The influence of the target compositions and annealing after deposition on the transmission of films and the gap energy was also evaluated.

The method of measuring of the parameters of precision frequency measures with the help of the frequency comparator CH7-308A/1 is presented, which compares the phase difference between the researched and the reference signals. The use of the CH7-308A/1 frequency comparator software and the software tools of the integrated Microsoft Office suite allows you to automate the processing of measurement results for precision frequency measures, to determine the relative frequency difference and frequency instability characteristics of the frequency and time signals. The advantages of this method are the ability to select measuring intervals from 1 s to 1 day or more. The method ensures automatic saving of measurement results and their long-term storage, easy search in the history of measurements by date and name of the measuring instrument, the ability to separate the time of observation for any periods and carry out their separate analysis, and, most importantly, to save the measurement results of the phase difference of the test and reference signals, for example, every second, in the form of a single file, which is easily transformed into a spreadsheet. This enables independently, using application software tools, to calculate the relative frequency difference between the researched and reference signals and the characteristics of the instability of the researched signal. Proposed methods of processing a series of numbers, which is a phase difference between the researched and reference signals, can be used not only in processing data from the frequency comparator CH7-308A/1, but also in the processing of data received from other devices, including the frequency meters to compare pairs of signals, such as CNT-90, CNT-91, Agilent 53131A, etc.

The developed hydrodynamic model of selective laser melting (SLM) considering shrinkage speed and the effect of the evaporation on the free surface of the melt is validated with experimental data for Ni-based powder SLM in a wide range of process parameters. The comparison of the main calculated output parameters (substrate melting depth and track width) with experimental data is held. The processing conditions with balling effect presence are also noted by the developed model.
