Abstract
The article considers the procedure of torque control, which is very popular in a wide variety of industries with many design features. In marine power engineering the problems of determining the forces, torque on the shaft and power are solved by means of torsiometers with torque sensors. The most widely used torque sensors are of capacitive, induction, strain gauge and photoelectric types. It has been stated that there are limitations in the process of torque control due to the susceptibility of systems to the electromagnetic interference, lack of a high degree of protection for electrical equipment and necessary recalibration. Fiber optic systems have found application in torque measurement systems in the oil and gas and aerospace industries. The use of such systems on ships is more expensive in comparison with the technologies used today, for example, the systems based on strain gauges. It has been proposed to use an inexpensive optical measuring system based on the Pound-Drever-Hall technique with using a foil-clad strain gauge and an aluminum torsion rod. There has been illustrated the system of torque control, the phase graphs for the Fabry-Perot resonator and the graph of the resonator transmission spectrum are presented, the reflection coefficient value is given. A method for measuring the phase of a reflected beam from a Fabry-Perot resonator is being considered, the injection current of a laser is modulated by means of an electric oscillator to generate side stripes in the electric field of a laser beam. The carried out studies and calculations contribute to improving the reliability of the coastal power system; the possibility of their use in marine electrical systems has been proved.

Summary
Керченский государственный морской технологический университет, Керчь, Российская Федерация. В системах измерения крутящего момента в нефтегазовой и аэрокосмической отраслях получили применение оптоволоконные системы. Проиллюстрирована система контроля крутящего момента, представлены фазовые графики для резонатора Фабри – Перо и график спектра пропускания резонатора, приведена величина коэффициента отражения. Ключевые слова: измерения, крутящий момент, электрические системы, частота лазера, метод Паунда – Древер – Холла, оптоволокно. С. Применение оптоволоконной оптической системы для контроля крутящего момента вала // Вестник Астраханского государственного технического университета. При обзоре литературы [1–4] были выявлены исследования, проводимые для контроля деформации с помощью метода лазерной синхронизации Паунда – Древер – Холла (метода улучшения стабильности длины волны лазера с течением времени). Для стабилизации частоты лазера при применении оптоволоконной системы контроля крутящего момента можно использовать метод синхронизации Паунда – Древер – Холла, который приводит в соответствие центральную частоту лазера с частотой внешнего высокоточного резонатора Фабри – Перо и фиксируется на краю внутри этого резонатора. No 3 Спектр пропускания на выходе резонатора Фабри – Перо представлен на рис. 1 с минимальной точностью для облегчения понимания
