The principles of scalar field analysis for dynamic systems are presented as applied to point-body and rigid body. The space of the dynamic system solutions (the phase space) is shown to be a scalar field of the shape of a hypersphere with moveable or stable center as related to a fixed point on the hypersphere surface; the point is specified by the initial states vector. The scalar field movement is proved to have a reciprocating character, i.e. is a retrograde one relative to the movement in the state space supplemented, in the case of a shifted center, with the hyperbolic component of its drive. It is demonstrated that with a fixed center, the scalar field movement possesses the feature of normal Perron dichotomy. Conditions for exponential Perron dichotomy to take place, in the case of shifted center, are specified. The scalar field hidden parameters such as constant and variable mass and Lorentz force are taken into consideration; the analysis confirms the conservation laws for kinetic energy and pulse, as well as the magnetizing effect for moving rigid body.

An algorithm is developed for compensation of atmospheric errors in trajectory information processing based of data from wide-area differential satellite navigation systems.

A model is proposed of optimal three-dimensional likelihood quantization of determined or random volume space by a set of equal quanta for which the probability of the quantized space representation reaches its maximum. The size of optimum quantum is determined by distribution of its zone of influence, boundary values of guaranteed probability, and an influence range parameter. A model for estimation of information quantity in the quantization space is presented.

A possibility of high gradient magnets construction from the commercially available NdFeB dipole magnets for the polarized atomic beam sources is described. Radial component of the magnetic field for quadrupole and six-pole magnets is measured at the middle plane of the magnet as function of the angle and along the magnet axis. Characteristics of magnetic field of the magnets calculated using COMSOL MultiPhysics software are compared to the experimental results. The feasibility to effectively use the software for 3D-simulation of the gradient multipole magnet systems to be developed is demonstrated.

The possibility of application of the results to development of optoelectronic devices for on-board detection complex is discussed. The results of measurements of basic parameters of the photodetector (dynamic range and sensitivity threshold) indicate technical possibility to obtain extremely high sensitivity with cooling the photosensitive layer down to the temperature not lower than 160—170 K and at high frame rate.

One-stage laser interferential chemical deposition of thin film periodical micro- and nanostructures from vapor phase without application of photolithography masks is studied experimentally. The experimental setup includes YAG:Nd3+ laser, vacuum chamber for process of structure deposition from volatile metal’s carbonyl vapor with transparent window for inletting laser irradiation into the chamber, opticalmechanical set to split the initial front into two coherent beams forming two-beam interference pattern on surface of transparent substrate. Dirhenium decacarbonyl is used as typical metalorganic compound. Results of the experiments are used to test a theoretical model describing the process of onestage laser interferential chemical deposition from vapor phase; in accordance with the model, the critical point is shown to be the pyrolysis process taking place mainly in the monolayer of carbonyl molecules adsorbed on the surface of transparent substrate. Application of two-beam interference is reported to provide a higher resolution of periodic topological pattern than projection photolithography and direct laser drawing.
