Krupkina T.Yu., Murashkina T.I., Pivkin A.G. Light flux power distribution in fiber-optic transducer’s space

The problems of light flux power distribution in fiber-optic transducer’s space are discussed. The relationships are determined between the transferred power and the distance from the emitting end to the collecting plane where either modulating elements or output optic fibers. The dependency between the transmission capacity on the external radius of illuminated area in different sections is also obtained.



Bazykin S.N., Bazykina N.A. A laser interferometer for angular displacements measurement

A laser interferometer circuit with an acousto-optical input modulator for angular displacements measurement is considered. The optical difference of beams distance at corner reflector system’s rotation is calculated.



Badeeva E.A., Gorish A.V, Krupkina T.Yu., etc. A tunnel-effect-based fiber-optic pressure sensor

New design and assembly process of a tunnel-effect-based fiber-optic pressure sensor are offered. The sensor is intended for high pressure measurements in ±100°C temperature range in space rockets and has reduced temperature and dynamic errors.



Badeev A.V., Murashkina T.I. Reflexometric displacement transducers

The paper analyzes design variants of reflexometric displacement transducers for non-contact measurements in 0…500 mm range and makes recommendations for their application.



Kapezin S.V., Bazykin S.N., Bazykina N.A. An interferometer with increased single-valuedness period

A circuit of a laser acousto-optical interferometer with increased single-valuedness period for linear quantities measurement is considered.



Rutkovsky V.Yu., Sukhanov V.M., Glumov V.M. A system for power train’s shaft torsion angle evaluation with the help of two induction rotating speed sensors. Part 2

The paper solves the problem of extending the informational capabilities of a standard rotating speed measuring system for a power train shaft of power plants. The problem is solved by additional processing of data arrays from discrete outputs of two induction rotating speed sensors with minimum intervention into the measuring system design.



Shirabakina T.A., Tevs S.S., Truphanov M.I. The features of machine vision systems calibration

Static and adaptive calibration techniques for machine vision systems are developed. Recommendations on calibration method selection subject to calibrated machine vision system’s parameters, ambient conditions, and calibration targets are made.



Furmakov E.F., Investigation of hydrodynamic properties of water surface with the help of free-floating sensors

The time changes of viscoelastic properties of free water surface are investigated with the help of free-floating submagnetic and non-magnetic sensors. The models of formation in long existing water surface are offered. The hypothesis is set up and justified experimentally that the near-surface water layer was formed by deuteration resulting of gradual water molecules replacement with heavy water in process of vaporization.



Kasatkin S.I., Polyakov O.P., Polyakov P.A., Rusakov A.E. The opportunities of implementing a hard-/software three-dimensional mouse system

The opportunities of hard-/software three-dimensional mouse system with magnetoresistive magnetic field sensors based on solving the inverse problem of magnetic location are discussed. The uniqueness of the solution of magnetic dipole space localization problem is analyzed.



Zhdankin V.K. Intrinsic safety barriers: selection criteria for measuring systems with resistance sensors

The paper lists the application features of intrinsic safety barriers in measurement circuits with thermal resistance converter and compares intrinsic safety barriers from various vendors.



Litvinov A.V., Nikolaev N.N. On the mechanism of MIS sensors sensitivity to hydrogen sulfide

Based on experimental data, the paper shows that MIS sensors sensitivity to hydrogen sulfide is determined by H2S molecules diffusion through the pores of the gate’s fine crystal palladium film to metal–dielectric interface and by molecules trapping. Up to 180°C molecules do not dissociate on the gate’s palladium film. The earlier detected sensor performance degradation under H2S exposure is reversible up to 180°C and does not impede MIS sensors application as sensing elements in gas analyzers.



Zhadobov M.V., Orlov I.Ya. An experimental system for in vitro studies of non-thermal biological effects of millimeter waves

This paper presents an experimental system for in vitro studies of non-thermal biological effects of millimeter waves in the 50…75 GHz frequency range. The system was used for investigating millimeter waves influence on biological membranes and stress-sensitive gene expression. Simulation results for power distribution on the surface of biological samples are presented.
