Abstract

Et system (10, 80) til påvisning av modulerte lasersig- naler har et minne (28) til lagring av fremkomster av flere forskjellige pulslntervaller l overensstemmelse med minst en på forhånd valgt karakteristikk for de forskjellige pulslntervaller og for å gi som utgang et signal når en vektet sum av antallet forskjellige pulsintervaller som blir talt, overskrider en på forhånd valgt terskelverdi.
