Abstract

To-farve sensoranordning (10) med fokalplanoppstilling ' som i bruk samtidig kan føle optisk energi innenfor første og andre bølgelengdespektra fra et område innenfor et synsfelt som er angitt her. Sensoranord- ningen (10) inkluderer et teleskop (12) for å kollimere den optiske energi innenfor synsfeltet l første og andre i det vesentligste overlappende stråler. Den første strålen inkluderer optisk energi Innenfor det første bølgelengdespektrum, og den andre strålen inkluderer optisk energi Innenfor det andre bølge- lengdespektrum. En kileformet strålesplitter (14) med et par ikke-parallelle reflekterende overflater (34, 36) omdirigerer optisk energi innenfor nevnte første og andre stråler til en fokuserende linse (18). Den fokuserende linsen projiserer den omdirigerte optiske energi fra den første og den andre strålen på første respektive andre region av et fokalplan. Første og andre detekteringsoppstillinger (20, 22) som erplassert i fokalplanet genererer elektriske signaler som et resultat av belysning .ved hjelp av den projiserte optiske energi.
