Abstract

En fiberoptisk strekksensor for måling av strekk langs minst én akse, samt sensorpakke og systemer inneholdende denne, omfattende en optisk fiber med minst ett Bragg-gitter, hvilket Bragg-gitter utgjør et sensorelement som er følsomt for mekanisk strekk, der Bragg-gitteret (-ene) er festet til en polymerfilm med en definert retning i forhold til minst ett ytre element på strekksensoren, f. eks. en ytterkant på filmen, der den optiske fiberen danner en i det vesentlige sirkulær løkke på filmen i hvilken løkke Bragg-gitteret(-ene) er plassert i en lineær del av løkken.
