Abstract

En fiberoptisk sensor anvender minst to bøyningsskiver som er atskilt fra hverandre langs en sentral akse. En fiberoptisk spole er festet til minst én av bøyningsskivene. En målemasse er anordnet mellom bøyningsskivene. Et første anslagsorgan er anordnet mellom målemassen og én fleksibel skive. Et annet anslagsorgan er anordnet mellom målemassen og den andre bøyningsskiven. De første og andre anslagsorganene er dimensjonert for å tilveiebringe plass mellom målemassen og de tilsvarende bøyningsskivene for å tillate normal bevegelse av bøyningsskivene, mens de interfererer med bevegelse av bøyningsskivene for å hindre uønsket ekstrem bevegelse. Den fiberoptiske sensoren kan brukes til OTDR-målinger av en akselerasjon for overvåkning i sanntid av oljefelt så vel som andre fiberbaserte interferometriske måleanvendelser. En koplingsstruktur kopler fortrinnsvis sammen de ytre kantene av de fleksible skivene med den massen som er festet til koplingsstrukturen.
