Abstract

En ultralyddetektor omfatter en opp- stilling av elektrisk isolerte elekt- roder (2) som er innstøpt i en ikke- ledende grunnmasse (4) av akustisk kon- struert materiale for å danne et sammen- satt legeme (5). En piezoelektrisk film (8) er bundet til legemet (5) ved hjelp av et isolerende klebemiddel (12), hvil- ket tilveiebringer en ohmsk/kapasitiv kopling mellom elektrodene (2) og re- spektive områder av filmen (8). Det signal som genereres mellom de indi- viduelle elektroder (2) og et elektrode- lag (18) som ligger over filmen (8), behandles for å tilveiebringe informa- sjon om lydtrykkfordelingen av en ultra- lydbølge. Anvendelsen av en ikke-ledende forbindelse mellom filmen (8) og elekt- rodene (2) letter fremstilling i vesent- lig grad, men tilveiebringer god ytelse.
