Abstract

Волоконно-оптические чувствительные элементы, работающие в отражательном или пропускающем режиме, используются почти во всех областях измерительной техники, а также для контроля промышленных установок, в медицинской диагностике, в авиационной и космической технике. При этом оцениваются воздействия механических, электрических, магнитных, акустических, термических и химических сигналов. Чтобы обеспечить наиболее простую оценку сигналов, лазерный свет из источника света 1 подключается в подводящее световое волокно 2, параллельно одной из двух его главных осей. В первом месте сплетения 3 свет направляется в первое базовое световое волокно 4, главные оси которого на 45повернуты относительно подводящего светового волокна 2. Во втором месте сплетения 5 свет попадает в имеющее такую же длину, как и первое световое волокно 4, второе световое волокно 6, которое своими главными осями повернуто на 90относительно первого базового волокна 4. В третьем месте сплетения 7 свет включается в низкодвоякопреломляющее световое волокно 8, которое сначала образует четвертьволновую петлю светопровода 9, а затем оптический чувствительный элемент 10. С помощью фазового модулятора (М) в сочетании с первым базовым световым волокном 4 можно статически или динамически воздействовать на сдвиг фаз света.
