Abstract

En avfølingsfiber for bruk i et distribuert temperaturavfølingssystem omfatter en optisk fiber som skal utplasseres i et måleområde der temperaturmåling skal utføres, som innbefatter et reflekterende element, slik som en skjøt mellom fiberpartier og et oppkveilet fiberparti posisjonert ved siden av en distal ende av det reflekterende elementet, idet det oppkveilede fiberpartiet hovedsakelig ikke bidrar noe til den rommessige utstrekning av den optiske fiberen når den er utplassert. l bruk, kan effekten av lys som forplanter seg fremover, på det reflekterende elementet som blir returnert for deteksjon ved hjelp av systemet, og som metter detektoren, elimineres ved å fjerne den del av det detekterte signalet som svarer til det oppkveilede partiet, hvoretter detektoren vil ha blitt gjenopprettet. De gjenværende deler av signalet kan brukes til å utlede den distribuerte temperaturprofilen siden disse delene representerer hele utstrekningen av avfølingsfiberen på grunn av mangelen på rommessig utstrekning for oppkveilingen. Oppkveilinger kan være tilveiebrakt på begge sider av det reflekterende elementet for dobbeltendetemperaturavfølingsteknikker.
