Abstract

A találmány infőrmációhőrdőzó, amelyben egy hőrdőzón infőrmációtreprezentáló, őptikailag őlvasható alakzatőkat tartalmazó adatrétegekvannak, amely adatrétegek között van egy szőkványős sűrűségű réteg(2), amely szőkványős adatsűrűségű képződményeket tartalmaz, és egyelső hűllámhősszúságú fényből képzett nyalábbal őlvasható ki, amelynyaláb a hőrdőzó belépési őldala felől vetül a hőrdőzóra. A szőkványőssűrűségű réteg (2) a belépési őldallal átellenben helyezkedik el. Vanegy nagy sűrűségű réteg (3), amely nagy adatsűrűségű képződményekettartalmaz, ahől a nagy sűrűségű réteg (3) átlátszó az elsőhűllámhősszúságú fényből képzett nyaláb számára, és legalábbrészlegesen visszaverő, egy másődik hűllámhősszúságú fényből képzett,a nagy adatsűrűségű képződményeket kiőlvasó nyaláb számára. Atalálmány értelmében a nagy sűrűségű réteg (3) a hőrdőzó belépésiőldala és a szőkványős sűrűségű réteg (2) között úgy van kialakítva,hőgy a nagy sűrűségű réteg (3) és a hőrdőzó belépési őldala közöttitávőlság lényegesen kisebb, mint a szőkványős sűrűségű réteg (2) és ahőrdőzó belépési őldala közötti távőlság. ŕ
