Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
122 words
AN INFRARED IMAGING SYSTEM USING A PLURALITY OF CONTIGUOUS ELEMENTAL FIELDS WHICH PROVIDE EXCELLENT FIELD DEFINITION WITH MINIMAL CROSS-TALK AND MINIMAL GAPS BETWEEN ADJACENT ELEMENTAL FIELDS, COMPRISING (A) A LONG FOCAL LENGTH OPTICAL MEANS DEFINING AN ENTRANCE APERTURE FOR THE INFRARED IMAGING SYSTEM, (B) AN ARRAY OF INFRARED DETECTORS, (C) EACH OF SAID DETECTORS IN SAID ARRAY HAVING A DETECTOR ELEMENT IMMERSED ON AN IMMERSION LENS, (D) SAID IMMERSION LENSES BEING POSITIONED IN ABUTTING RELATIONSHIP AND IN THE FOCAL PLANE OF SAID OPTICAL MEANS SUCH THAT EACH LENS ACTS AS A FIELD LENS WHICH IMAGES THE ENTRANCE APERTURE OF THE SYSTEM ON ITS ASSOCIATED DETECTOR ELEMENT TO FORM CONTIGUOUS ELEMENTAL FIELDS OF THE ENTRANCE APERTURE WITH MINIMAL GAPS BETWEEN THE ELEMENTAL FIELDS.
