ALADIN best\u00e5r av en kraftig laser og et stort teleskop koblet til en sv\u00e6rt f\u00f8lsom mottaker. Laseren sender korte pulser med intenst lys ut i atmosf\u00e6ren. Dette lyset spres av gassmolekyler, st\u00f8vpartikler og vanndr\u00e5per.<\/p>\n<p>En del av det tilbakespredte lyset fanges opp av romfart\u00f8yets teleskop og sendes til mottakeren om bord.
