Abstract

Et selvorlenterende vertikalfølsomt akselorometer er vist for måling av en vertikal akselerasjonskomponent uavhengig av akselorometerets orientering. Akselorome- teret ifølge den foreliggende oppfinnelse omfatter et sfærisk plastskall (12) med et antall perforeringer (14) i seg og en tynn film (16) av metallbelagt piezoelektrisk polymer bundet til dens utside, som danner en liten diafragma ved hver perforering (14). Som reaksjon på akselerasjon utvikles dynamisk trykk i en fluidmasse (24) som delvis fyller opp det sfæriske plastskall (12) som skaper eri deformasjon og resul- terende ladning i hver lille diafragma av piezo- elektrisk polymer. Den enorme forskjell i densitet mellom fluidmassen (24) og luften .1 det gjenstående volum av det sfæriske plastskall tillater ladningen utviklet l hver lille diafragma under fluldtrykket å bidra kun til den vertikale akselerasjonskomponent påført fluidmassen (24). I en foretrukket utførelse av den foreliggende oppfinnelse er det selvorienterende vertikalfølsomme akselorometer montert inne l et lavdensitets åpencellet skum og utnyttet l en marin seismisk hydrofonkabel der orienteringen av hvert akselorometer ikke er enkelt å styre eller kontrollere.
