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.

Abstract: An integrated photonics chip for thermal imaging comprises a photonics substrate including a plurality of receiver elements. Each receiver element comprises a first grating coupler optically coupled to a first waveguide filter and configured to receive a first wavelength of light at a given angle, with the first waveguide filter configured to pass the first wavelength of light; and a second grating coupler optically coupled to a second waveguide filter and configured to receive a second wavelength of light at the given angle, with second waveguide filter configured to pass the second wavelength of light. Each receiver element receives the wavelengths of light from an object of interest that emits the light due to blackbody radiation, and receives the wavelengths of light at respectively different angles. Each grating coupler receives a unique wavelength of light with respect to the other wavelengths of light received by the other grating couplers.

Abstract: Devices including graphene quantum dots yield extremely high performance THz bolometers, by measuring the current of hot electrons formed in the graphene source and drain electrodes of the device and propagating through the graphene quantum dot connected thereto. Devices may also include additional materials such as MoS2, as well as one or more gate electrodes to alter performance as needed.

Abstract: A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

Abstract: Apparatus and associated methods relate to creating corrected images of a scene for a terminal-imaging seeker using an electrically-controllable coded-aperture mask pattern embodied in a programmable spatial light modulator. The coded-aperture mask pattern includes a plurality of pinhole-like apertures, each of which is configured to perform pinhole-like lensing of the scene. The plurality of pinhole-like apertures form a multiplex of overlapping images on a focal plane array aligned with the optical axis. An image processor reconstructs, based on a configuration of the plurality of pinhole-like apertures and the multiplex of overlapping images, a single image of the scene.

Abstract: An infrared (IR) imaging system for determining a concentration of a target species in an object is disclosed. The imaging system can include an optical system including a focal plane array (FPA) unit behind an optical window. The optical system can have components defining at least two optical channels thereof, said at least two optical channels being spatially and spectrally different from one another. Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA. One or more of the optical channels may be used in detecting objects on or near the optical window, to avoid false detections of said target species.
