  • Publication number: 20250244472
    Abstract: A millimeter wave (MMW) display arrangement is envisioned to comprise a MMW camera that has an array of single pixel MMW detectors that capture MMWs and pipe MMW intensity data, of the captured MMWs, to a display screen where an MMW picture is assembled from a plurality of MMW sub-images from different portions of a scene scanned by the MMW camera. Each of the MMW sub-images comprise a plurality of contrast cells each of which are produced from a corresponding single pixel MMW detector. The MMW camera constructs the MMW picture by changing perspectives of the scene by way of either moving the camera or by shifting positions of a mirror between the camera and scene.

  • Publication number: 20240328864
    Abstract: The disclosed MMW wave sensing camera calibration arrangement that generally includes a millimeter wave camera that uses an energy emission calibration panel as a calibration standard. The MMW camera is positioned opposite the calibration panel in the MMW camera's field-of-view. The calibration panel is held at a constant temperature to provide a standard emission of millimeter waves that is sensed by an MMW sensor to set or otherwise calibrate the MMW camera to a baseline emissivity value corresponding to the panel. The MMW camera is linked to a microprocessor and non-transient computer memory containing a calibration routine that is configured to reset the baseline only when nothing obstructs the calibration panel's field-of-view. A visual display is linked to the MMW camera and configured to display an MMW signature of a metal object that is disposed on a person's body when the person's body is in the field-of-view, the metal object concealed by clothing worn over the person's body.

  • Patent number: 11886057
    Abstract: An optoelectronic system includes a concentration layer, a modulation layer including an array of light modulators, an exit layer that receives the modulation layer output having a modulation layer output spatial distribution and remaps the modulation layer output spatial distribution to a modified spatial distribution. A collector layer receives the modified spatial distribution to produce a collector layer output. A detector receives the collector layer output. A processor controls the modulation layer and receives the detector output to generate an image. The collector layer can receive the modified spatial distribution at a plurality of collector layer inputs and combine the plurality of collector layer inputs at a collector layer output. Modulators can be configured to direct couple modulated light to a collector layer, without using an exit layer. Configurations with spatial light modulator modules and sub-modules are described.

  • Patent number: 11777220
    Abstract: An apparatus includes a horn having a horn body including at least one horn sidewall defining a first opening that tapers down to a second opening in a direction of elongation and a port that is tubular and dimensionally uniform transverse to the direction of elongation and extends in the direction of elongation from a first port end that is in communication with the second opening to a second port end that defines an external opening. A dielectric rod includes a rod length extending between a first rod end and a second rod end with the first rod end extending through the external opening of the second port end and into the port cavity such that the first rod end is in a spaced apart relationship from the port sidewall along the light path.

  • Patent number: 11378829
    Abstract: A spatial light modulator system includes a concentration layer including an array of optical concentrators, such that each concentrator concentrates a portion of an input light beam. A modulation layer includes an array of light modulators each in optical communication with one of the optical concentrators for modulating the portion of the input light beam. The light modulators are spaced apart from one another in the modulation layer to form gaps between adjacent ones of the light modulators. A coil of each light modulator can surround a Faraday element or core containing a Faraday material to control a magnetic state of a Faraday material responsive to control signals.
