摘要： A position of a feature in a scene is located by forming an image of the feature using a segmented array having a plurality of array subelements. Each of the array subelements has an output signal. The output signals from at least two spatially adjacent array subelements are cooperatively analyzed to establish a data set reflective of an extent to which output signals responsive to the image of the feature are produced from exactly one or from more than one of the adjacent array subelements. The data set is used to reach a conclusion as to a location of the image of the feature on the segmented array. Increased positional accuracy is attained with no loss of sensitivity.

摘要： A monolithic body (31) has a compound optical surface that defines a centrally located lens element (31B) that is transmissive to light having wavelengths of interest, such as infrared radiation (IR), and a reflector (31B) disposed about the lens element that is reflective to the light. The monolithic body is comprised of a material selected for fabricating a refractive lens element. The compound optical surface has a centrally located portion defining the lens element surrounded by a generally curved surface region having a reflective coating that defines the reflector. The centrally located portion may be coated with an anti-reflection coating. The compound optical surface is preferably formed in one operation, such as one that uses a diamond point turning operation.

摘要： An infrared sensor element having an antenna coupled directly into a rectifier. Infrared radiation impinging the antenna induces an alternating current. The rectifier converts the alternating current into a rectified signal. The rectified signal corresponds to a magnitude of the incident infrared radiation impinging the antenna, and can be used for detection and imaging operations. Coupling the antenna directly into the rectifier eliminates the need for a photodetector. The wavelength of sensor elements can be separately tuned. A sensor made up of a plurality of such sensor elements can operate in a time-division multiplexed mode sensing different infrared bandwidths in separate time segments. Two or more sensors each made up of a plurality of sensor elements can be co-located in a single focal plane and operated separately to detect infrared radiation in different bandwidths. A sensor element can also operate in bandwidths other than infrared.

摘要： A wide-angle IR imaging system (1A) has an entrance aperture (40) for admitting IR from a scene and a dewar (4A) that contains a coldshield (3) that encloses a cooled IR detector (2) disposed at an image plane (2A). The dewar includes a dewar window (4), and an optical axis of the IR imaging system passes through the dewar window and the image plane. The IR imaging system further includes a plurality of uncooled optical elements (22, 24, 26, 28) disposed along the optical axis between the entrance aperture and the dewar window, and a plurality of generally annular reflector segments (18A, 18B) disposed around the optical axis between the dewar window and the entrance aperture. Each of the reflector segments has a reflective surface that faces the dewar window. An opening through an outermost reflector segment furthest from the dewar window defines an effective cooled aperture stop, or warm stop (20A) of the IR imaging system, and at least one of the optical elements (22) is disposed between the effective cooled aperture stop and another one of the reflector segments (18A) that is located nearer to the dewar window. In the preferred embodiment the at least one optical element, and the reflector segment that is located nearer to the dewar window, are comprised of a single monolithic body (31) that has a compound optical surface.
