Patent number: 10267997Abstract: A scene projector including an array of light emitting pixels, a tunable filter element, and a spatial light modulator. The tunable filter element is optically coupled to the array of light emitting pixels such that light emitted from the array of light emitting pixels is passed through the tunable filter element as filtered light. The spatial light modulator is optically coupled to the array of light emitting pixels and is configured to generate transmitted light by interacting with the filtered light to control at least one of an amplitude, a phase, and a polarization of the filtered light.Type: GrantFiled: November 11, 2015Date of Patent: April 23, 2019Assignee: RAYTHEON COMPANYInventors: Justin Gordon Adams Wehner, Duane D. Smith, Edward Peter Gordon Smith, Adam M. Kennedy

Patent number: 8691614Abstract: An image detector comprises a plurality of photosensitive detector unit cells interconnected to a plurality of integrated circuits by a plurality of direct bond interconnects. Each unit cell includes an absorber layer and a separation layer. The absorber layer absorbs incident photons such that the absorbed photons excite photocurrent comprising first charged carriers and second charged carriers having opposite polarities. The separation layer separates the first charged carriers for collection at one or more first contacts and the second charged carriers for collection at one or more second contacts. The first and second contacts include the direct bond interconnects to conduct the first charged carriers and the second charged carriers from the unit cells in order to facilitate image processing.Type: GrantFiled: April 23, 2013Date of Patent: April 8, 2014Assignee: Raytheon CompanyInventor: Edward Peter Gordon Smith

Publication number: 20120280350Abstract: According to one embodiment, a position sensitive detector (PSD) comprises a plurality of layers, including a substrate layer, an absorber layer, a barrier layer, a sheet layer, and a contact layer. The absorber layer absorbs incident photons such that the absorbed photons excite positive charges and negative charges in the absorber layer. The barrier layer collects a photocurrent from the absorber layer, the photocurrent comprising either the positive charges or the negative charges. The sheet layer provides resistance to control the flow of the photocurrent between a point of incidence of the photons and a plurality of interconnect contacts. The contact layer comprises the interconnect contacts, each interconnect contact operable to conduct the photocurrent to one or more electrical components external to the PSD. The position sensitive detector facilitates determining the point of incidence of the photons according to a relative amount of photocurrent associated with each interconnect contact.Type: ApplicationFiled: May 3, 2011Publication date: November 8, 2012Applicant: Raytheon CompanyInventors: Edward Peter Gordon Smith, Borys Kolasa
