ALADIN best\u00e5r av en kraftfull laser och ett stort teleskop kopplat till en mycket k\u00e4nslig mottagare. Lasern s\u00e4nder ut korta pulser av intensivt ljus in i atmosf\u00e4ren. Detta ljus sprids av gasmolekyler, dammpartiklar och vattendroppar.<\/p>\n<p>En del av det bak\u00e5tspridda ljuset f\u00e5ngas upp av rymdfarkostens teleskop och skickas vidare till mottagaren ombord.
