Abstract
Akseleromefre for å bestemme akselerasjon og fremgangsmåter for å produsere et akselerometer er beskrevet. I én utførelsesform omfatter akselerometeret en ramme, en masse bevegelig opphengt på rammen, et fast element som har en avrundet overflate som ikke beveger seg med massen, et bevegelig element som har en avrundet overflate som beveger seg med massen, og en avfølingskveil av optisk bølgeleder kveilet omkring de avrundede overflatene for å detektere bevegelse av massen i respons på akselerasjon basert på interferometrisk avføling av en endring i lengden av avfølingskveilen. En fremgangsmåte for å produsere akselerometeret omfatter opphenging av massen i rammen og kveiling av den optiske bølgelederen omkring de avrundede overflatene. Følsomhet og lav fabrikasjonskostnad for akselerometrene muliggjør bruk av dem til integrasjon i en seismikkabel for havbunnen. Videre kan akselerometeret være et på-linje eller et på-tvers akselerometer avhengig av arrangementet innen rammen.
