Abstract

Światłowodowy czujnik odległości, który wykorzystuje kontrolowane wprowadzanie strat zgięciowych w światłowodzie i zawiera przyłączony do źródła światła oraz układu detekcyjnego co najmniej jeden tor światłowodowy zawierający co najmniej światłowód czujnikowy jaki w co najmniej jednym, miejscu jest połączony z modułem zwijającym, a poza obszarem zamocowania lub w tym obszarze fragment toru światłowodowego wyprowadzony jest poza moduł zwijający. Sposób pomiaru odległości z wykorzystaniem czujnika odległości polegający na umieszczeniu w obszarze połączenia co najmniej dwóch elementów między elementami, tak że czujnik odległości podlega wydłużeniom oraz skróceniom, a następnie wprowadzenie do toru światłowodowego sygnału optycznego pochodzącego ze źródła światła (1), a następnie sygnał prowadzi się transmisyjnie lub odbiciowo co najmniej jednym torem światłowodowym tak, że w skutek wydłużenia lub skrócenia czujnika wprowadza się straty zgięciowe i mierzy się moc świetlną prowadzonego sygnału po wyprowadzeniu toru światłowodowego poza obszar modułu zwijającego (2).
