摘要： A small array of antenna-coupled infrared bolometer detectors is connected in parallel. This small array is suitable as an individual area-receiving pixel of an infrared focal plane array. These pixels will have better coupling efficiency to extended sources than are possible with individual antenna-coupled sensors, which have a spatial response on the order of one wavelength in dimension. This pixel can be used to provide the advantages of antenna-coupled IR sensors (e.g., fast response, wavelength tuning, and polarization tuning) while increasing the collection efficiency of the sensors to non-laser sources. When integrated into focal plane arrays, these detectors can be used in remote-sensing systems to facilitate enhanced image recognition, feature extraction and image-clutter removal. A preferred version of the pixel forming the focal plane array antenna has a plurality of two parallel longitudinal metal antenna arms extending outward and opposite from an infrared (IR) bolometer sensor to separate parallel contact pads connected in turn to a means for receiving the output from said antenna. Application areas can include earth-resource mapping, pollution monitoring, and general surveillance.

摘要： According to one embodiment, a radiation sensor comprises a first pixel and a second pixel. The first pixel comprises a first plurality of antenna elements, a first photodetector, and one or more first feed lines coupling the first plurality of antenna elements to the first photodetector. The second pixel comprises a second plurality of antenna elements, a second photodetector, and one or more second feed lines coupling the second plurality of antenna elements to the second photodetector.

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.
