Overview of high performance fibre-optic sensing

Abstract: An overview of fibre-optic interferometry based sensing is given, particularly as it applies to high-performance sensing applications. The operation of a fibre-optic interferometer as a sensor is reviewed. The sensitivity limitations of a fibre-optic sensor are derived, and the system impact of multiplexing many sensors together is explored. A review of the development of the fibre-optic acoustic transducer is presented, as well as system applications and future trends in fibre-optic interferometric sensing.

“…In many fiber-based systems, such as interferometric fiber-optic sensors [1][2][3][4] , fiber lasers [5][6][7] , and fiber-delay-line stabilized lasers 8 , the fundamental resolution or frequency stability is limited by the intrinsic thermal noise inside optical fibers. Thus, an experimental and theoretical understanding of the thermal noise in optical fibers is important.…”

“…В последнее время значительно возрос интерес к волоконно-оптическим системам с аналоговыми оптическими сигналами и аналоговой модуляцией. Это системы опроса и предварительной обработки сигналов волоконно-оптических датчиков [2] и радиофотонные системы генерации, пе-редачи и обработки аналоговых СВЧ-сигналов [3,4]. Здесь возбуж-даемые электрическими управляющими сигналами поверхностные и объемные акустические колебания модулятора даже на относительно Рис.…”
