Abstract

Et optisk akselerometer innbefatter anordninger for å endre lengden av minst en optisk fiber som reaksjon på akselerasjon funksjonelt koblet til den minst ene optiske fiberen. Fiberen og anordningen for endring av lengden er innelukket i et trykkompensert hus. Huset er fylt med et hovedsakelig ukomprimerbart fluid eller en gel. Et seismisk flerkomponentsensorsystem består av minst to slike akselerometere.
