Abstract

Skaner obrazu zawiera źródło światła oświetlającego i hybrydową soczewkę oświetlającą. Hybrydowa soczewka oświetlająca (170) zawiera pierwszą powierzchnię Fresnela (175), skierowaną do źródła światła oświetlającego, i drugą powierzchnię (176), mającą na sobie układ mikrosoczewek. Pierwsza powierzchnia Fresnela jest skonfigurowana tak, aby kierować światło odbierane ze źródła światła oświetlającego w stronę drugiej powierzchni dla wytwarzania światła oświetlającego w kierunku przedmiotu docelowego przez układ mikrosoczewek na drugiej powierzchni.
