Description
465 645
Den elektrooptiska sensorn avkänner kontinuerligt havsytan i delytor såsom an-
givits i fig 2. Varje delyta motsvarar en hydrofongrupp (kanal) i dagens in-
samlingssystem. Positionen av varje avsökt delyta (12) relateras till en refe-
renspunkt genom att den radiella vinkeln (u) och vertikala vinkeln (v) med
vilken ljusstrålen sändes och mottages registreras vid varje mättillfälle.
Med dagens hydrofonbaserade system kommer också oönskade signaler att registreras
tillsammans med primärsignalerna. Sådana störningar utgörs vanligen av större
och mindre havsvägor. Eftersom registreringen av den reflekterade ljussignalen
sker över en delyta kan arean hos denna delyta väljas på så sätt att dessa yt-
genererade störningar inte ligger i fas över avsökningsytan. De seismiska pri-
märsignalerna kommer däremot att träffa havsytan med en vinkel som är nära
90 grader och blir således registrerade i fas över hela avsökningsytan (delytan).
