These fiber gratings are designed for measurement of temperature, linear and bending tension and allow by 1-2 orders increase their resolution. Shows the effect of increasing the sensitivity of electrophysical parameters definition using Bragg structures with a phase shift in the coaxial cable.</p>fiber Bragg gratingBragg structure in the coaxial cablephase shiftsensortemperaturelinear and bending tensionresolutiondielectric permittivityволоконная брэгговская решеткабрегговская структура в коаксиальном кабелефазовый сдвигдатчиктемпературалинейное и изгибное натяжениеразрешающая способностьдиэлектрическая проницаемость
