Abstract

Et automatisk fokuserende system som omfatter minst en mikrospeil-rekkelinse, en billedsensor og en signalprosessor. Mikrospeil-rekkelinsen avbilder et objekt og fokuserer bildet på billedsensoren. Billedsensoren mottar lyset og omdanner fotoenergien av lyset til elektrisk energi i form av et elektrisk signal. Billedsensoren sender det elektriske signalet, som bærer billeddata vedrørende objektet, til signalprosessoren. Signalprosessoren mottar det elektriske signalet, sammenligner billedkvaliteten av de avbildede dataene med dens fokuskriterier, og genererer et reguleringssignal, som den sender til mikrospeil-rekkelinsen for å justere brennvidden til mikrospeil-rekkelinsen. Denne iterative prosessen fortsettes inntil kvaliteten på billeddataene møter fokuskriteriene, og prosessen er fullført innen etterbilledshastigheten til det menneskelige øyet.
