Abstract

Hologram og diffraksjonsgittere er beskrevet, der nærværet av en "nøkkelfarge" (magenta) tillater en observatør å identifisere posisjonen der alle andre farger av hologrammet kan utvetydig bestemmes. To sett av spektra (60, 70) er framskaffet slik at ved en gitt vinkel (13) vil en referansestråle av innfallende hvitt lys (10) belyse hologrammet eller diffraksjonsgitterkomposisjonen og bevirke at en observatør (11) ser fargen "magenta" som skal brukes som referanse "nøkkelfarge".
