  • Study of radiation sources of automatic control system of optical parameters of fiber-optic sensors

    Periodicals of Engineering and Natural Sciences, 2025
    The prime objective of this experimental study is to check the influence of radiation on the performance and stability of a fiber-optic sensor’s control system. It examines the key issues caused by radiation and proposes solutions to improve the accuracy of measurements. For this test, a model of radiation exposure was created using special gamma and beta rays to observe how they influenced signal flow and the sensors’ reaction. Special ways of analyzing spectra and constant observation systems were used to detect changes and decreases in the optical signals resulting from radiation. As the radiation dose increases, it begins to degrade the quality of the data, ultimately leading to a 15% weakening of the signals at 500 Gy. Nonetheless, the use of special protective materials and programs managed to cut radiation exposure by a staggering 70%. The study demonstrates that enhancing both the radiation-hardened components and dynamic controls in fiber-optic sensors improves their reliability in areas with high radiation exposure. Such discoveries offer significant benefits for nuclear facilities, aerospace, and medical imaging, as resistance to radiation is crucial in these fields. These solutions play a role in strengthening the performance of automatic control for fiber-optic sensors.

    Technical monitoring of building structures is necessary to improve the efficiency and safety ones. Early diagnosis in real time and timely notification of the danger of destruction of a monolithic reinforced concrete building structure, as well as the finding of the exact location of cracks formation is a very urgent problem. Development of control tools for the timely identification of hidden defects in extended building structures, monolithic reinforced concrete foundations etc. requires experimental studies of fiber-optic sensors in the observation systems. In the first part of the study, an overview of experimental investigations related to building structures monitoring using fiber-optic sensors (FOS) was carried out. The second part contains a summary of our experimental studies on the control of the technical condition of building structures. The optimal parameters for the configuring system are proposed. It is shown that under mechanical stress on FOS, the spectrum of the light spot changes. This makes it possible to determine the exact numerical values of the deformation. The use of the G652 standard optical fiber as a distributed source for continuous monitoring of the technical condition of buildings and structures allows monitoring changes in the parameters of mechanical loads, stresses, and deformations. A distributed FOS can be both a sensing element and a communication channel. The use of fiber in the control system will allow achieving high energy efficiency, since the attenuation of the optical signal in the fiber is very small. The results convincingly show that with the means of quasidistributed sensors, it is possible to reliably identify the damaged area, and using the optical reflectometry method to determine the place of destruction with an accuracy of one meter.

    Design of control tools for the timely identification of hidden defects in monolithic reinforced concrete foundations, beams, and other extended building structures requires experimental studies of fiber-optic sensors (FOS) in monitoring systems. In the first part, an overview of experimental studies related to the monitoring of building structures using FOS was carried out. This paper discusses our experiments on the observation of the technical condition of building structures. The optimal parameters of the monitoring system are proposed. It is shown that under mechanical stress on FOS, the spectrum of the light spot changes. This makes it possible to determine the exact numerical values of the deformation. The use of optical fiber of the G652 standard as a distributed source for continuous monitoring of the condition of buildings and structures allows monitoring changes in the parameters of mechanical loads, stresses, and deformations. The dependence of the destruction of the optical fiber material with the cyclic load factor is founded. The main factors in the development of fatigue cracks in optical fiber are the amplitude of stresses and deformations, the duration of loading cycles. The results convincingly show that by means of quasi-distributed sensors it is possible to reliably identify the damaged area, and using the optical reflectometry method to determine the place of destruction with an accuracy of one meter.
  • Physical and Mathematical Models of Quantum Dielectric Relaxation in Electrical and Optoelectric Elements Based on Hydrogen-Bonded Crystals

    Crystals, 2023
    The quantum statistical properties of the proton subsystem in hydrogen-bonded crystals (HBC) are investigated. Based on the non-stationary Liouville operator equation (taking into account a number of assumptions established in the experiment), a quantum kinetic equation is constructed for the ensemble of non-interacting protons (an ideal proton gas) moving in the crystal potential image perturbed by the external electric field. The balanced density matrix for the unperturbed proton subsystem is constructed using the quantum canonical Gibbs distribution, and the non-balanced density matrix is calculated from the solutions of the nonlinear quantum kinetic equation by methods in linear approximation of perturbation theory for the blocking electrode model. Full quantum mechanical averaging of the polarization operator makes it possible to study the theoretical frequency-temperature spectra of the complex dielectric permittivity (CDP) calculated using quantum relaxation parameters that differ significantly from their semiclassical counterparts. A scheme is presented for an analytical study of the dielectric loss tangent in the region of quantum nonlinear relaxation in HBC. The results obtained in the given paper are of scientific interest in developing the theoretical foundations of proton conduction processes in energy-independent memory elements (with anomalously high residual polarization) based on thin films of ferroelectric materials in the ultralow temperature range (1–10 K). The theoretical results obtained have a direct application to the study of the tunneling mechanisms of spontaneous polarization in ferroelectric HBC with a rectangular hysteresis loop, in particular in crystals of potassium dideutrophosphate (KDP), widely used in nonlinear optics and laser technology. The quantum properties of proton relaxation in HBC can be applied in the future to the study of solid-state electrolytes with high proton conductivity for hydrogen energy, capacitor technology (superionics, varicodes), and elements of MIS and MSM structures in the development of resonant tunnel diodes for microelectronics and computer technology.
