Peculiarities of the spatial behavior of the amplitude zero resulting from scattering of coherent radiation at random rough surfaces are studied. The optical correlation technique is proposed for diagnostics of phase singularities at a complex speckle field. It is shown that the coordinate distribution of the phase singularities at the field with coaxially imposed reference wave provides visualization of strongly scattering objects.

According to the results of the research, established that the varnish layer influence on the color indicators of the prints for triad paints of different colors are quite stochastic. In general, it is possible to allocate some dependence of color change indicators of prints under layer of a matte varnish Soft Touch influence. The most expressed change in color is characteristic of mixed test fields, which visually reflected by a decrease in color saturation the image becomes brighter. Composite gray and black colors, based on the triad, lose saturation in deep shadows, and as a result become lighter. A black color, incompatible, when applying a layer of varnish acquires a chromatic part. Based on the analysis of experimental data, recommend use a comprehensive approach when varnishing printed products with Soft Touch varnish. First, it is necessary to carry out test printing on new materials to set up the effect of the varnished coating on color change. Secondly, having information about the nature of the color change, make them at the stage of prepress preparation of the original layouts. Thirdly, to select for reproduction of the image, after varnishing have minimal color differences.

Billions of banknotes in their daily circulation are determined as one of the important spreading ways of thousands of different microbes among the world's population. Therefore, the main factors influencing the degree of microbiological contamination of banknotes are considered. The influence of varnishing technological parameters, in particular the type of varnish cure on the surface, anilox roll line count, and anilox roll transfer volume, on the resistance of banknotes contamination, was studied to determine the option of UV varnishing, which will be the most optimal to improve the resistance of banknotes against to contamination. Also, the innovative technological processes of banknote surface antibacterial protection are proposed, in a particular banknote surface coating with varnishes that include silver nanoparticles, which have great bactericidal action. Methods of synthesis and stabilization of silver nanoparticles in aqueous solutions and organic solvents used for the inclusion into water-soluble and UV varnishes are considered. Conditions for the inclusion of silver nanoparticles in water-soluble and UV varnish have been established. The morphology and spectral characteristics of the obtained silver nanoparticles were studied. The methodology of decolorization of aqueous solutions of silver nanoparticles was developed in the paper, it was proposed to use such polymers as polyvinylpyrrolidone and sodium polyphosphate to increase the stability of nanoparticles. The influence of varnish compositions - water-soluble and UV varnishes - on the stability and spectral characteristics of silver nanoparticles has been studied.

Breath analysis is an emerging research field with tremendous potential for advance personalized, non-invasive health screening and diagnostics,while new sampling instrumentation tools andanalytical detection methods are developed. Notwithstanding of the quick development of commercially and researcher-built experimental samplers, no robust and repeatable VOCs’ profile technologies have been clinically validated. Such is due to lack of an optimal standard procedure for selective breath sampling which ends in a wide range of contradictory reported results. Challenges of most breath samplers are also related to the substances’ concentrations that are source (oral cavity, oesophageal and alveolar) dependent and their low values (in ppbv - pptv range). Here, we present a suitable and novel technology for selectively sampling exhaled air regarding the subject’s: age, gender, metabolic production of CO2, smoking habits, nutrition and health conditions. The technology was aimed to perform real time flow measurements and collect a pre-determined portion of exhaled air by synchronizing a previously modelled respiratory cycle with the breathing cycle of the user. Through real-time synchronization of breathing cycles, the system can detect optimized sampling instants by machine learning-based algorithm. A first set of tests was conducted to evaluate the robustness and efficiency of the software’s sampling algorithm with two cohorts of participants (n=15 and n=30) with different age groups (2-5 years old and 18-27 years old, respectively). The ability to selectively differentiate exhaled air was also tested through collection and posterior analysis of oesophageal and alveolar air samples obtained from an independent cohort of university students (n=31). Although it requires instrumentation improvements and optimization the breath sampling technology coupled with an efficient analyser device (GC-IMS), the results herein presented suggest a promise step forward in breath sampling adapted to users’ age, genre and physiological condition.

This study examines a model for analyzing the behavior of carbon nanoparticles in speckle field under the influence of optical forces. As a result of computer modeling, optical parameters of carbon nanoparticles were calculated, which made it possible to assess the optical forces (gradient, absorbing and scattering components) acting from internal energy flows in the optical field on carbon nanoparticles. The influence of size of carbon nanoparticles on the ratio of components of optical force is analyzed. Conditions are defined when the amount of gradient force will be significant, which will set the spatial movement of carbon nanoparticles in the area of the minimum, in particular in singular points.

The level of silicon p-i-n photodiodes responsivity depending on thickness of the chromium sublayer on the back side of the device crystal, which is deposited to improve adhesion of gold, was studied. Transmission spectra of the chromiumfilm at its different thicknesses were obtained. It was found that starting from the sublayer thickness of 17 nm and less, the transmittance changes by one percent, which does not lead to an increase in photoresponsivity with a further decrease in the thickness of chromium.

he paper presents the approximation of the three-dimensional optical transfer function of diffraction-limited non coherent optical systems with axial symmetry. This approximation is based on the analytical expression for identification of three-dimensional spatial cutoff frequencies that specifies the spatial bandwidth in three-dimensional space of spatial harmonics. It does not require numerical integrations. The proposed techniques makes calculation of the three dimensional optical transfer functions accurate, easy and fast. It can be applied for performance evaluation, analysis of spatial resolution, computer simulation of imaging systems etc.
