Abstract: An imaging system including a dichroic beamsplitter configured to be angled at least at a first angle and a second angle wherein when angled at the first angle imaging at a broad band wavelength spectrum and at least one of laser designation and laser ranging performed with a laser beam occurs with the dichroic beamsplitter and when angled at the second angle the imaging at the broad band wavelength spectrum and laser spot tracking performed with a laser beam occurs through the dichroic beamsplitter. Another system and method are also disclosed.

Abstract: A vehicle including a scanning imaging system includes a vehicle body having an outer surface, a propulsion source, and an optical window secured to the outer surface of the vehicle positioned on an optical axis for transmitting electromagnetic radiation received from a portion of an area of interest to the scanning imaging system. The scanning imaging system includes a first achromatic prism pair having prisms with different materials that have different refractive properties, and a second achromatic prism pair having prisms with different materials that have different refractive properties, both positioned on the optical axis. A camera fixed in location is optically coupled to form images from the electromagnetic radiation after being bent by the achromatic prism pairs. A motor including a controller independently rotates the first and second achromatic prism pairs about the optical axis for scanning within the area of interest.

Abstract: A method and apparatus for optical damage assessment using an existing imaging focal plane array and a fixed or moving set of optics and filters. Advantages include cost reductions and improved reliability due to fewer components and therefore fewer points of failure.

Abstract: An apparatus combining an optical sensor and a bomb impact assessment system, and corresponding method for facilitating bomb impact assessment, comprising means for receiving an optical signal, means for splitting off a portion of the optical signal from a primary optical path to form a secondary optical path, a lens in the secondary optical path, the lens comprising a plurality of facets generating a plurality of tertiary optical paths, means for combining signals from the primary and one or more of the tertiary optical paths, means for detecting the combined signals, and means for projecting onto a focal plane array bomb impact assessment data comprising detected signals from one or more of the tertiary optical paths.

Abstract: A window baffle assembly has a multi-element segmented window having a first surface adapted to receive at least one wavelength of radiation from an optical system, a baffle housing positioned proximate at least a portion of the first surface of the segmented window, and a plurality of baffle elements each affixed between positions on the baffle housing and offset from the first surface of the window. At least a portion of the plurality of baffle elements are in a Field of View of the optical system at an operational angle. The surface of the baffle elements are adapted to absorb at least a portion of the energy of the radiation and oriented to scatter the radiation. Each baffle element comprises a leading edge and an opposing trailing edge, the leading edge oriented toward the first surface of the window and the trailing edge oriented to point toward a central point of the optical system. A method of manufacturing a window baffle assembly is also provided.

Abstract: A hydrated granular fly ash composition is disclosed. The granular fly ash may be transported with minimal dust problems while maintaining its capacity to act as a solidifying agent at a remote destination. The process for producing the fly ash involves evenly dispersing a pre-determined amount of water into the fly ash so that it is transformed into a granular form substantially eliminating dust production. An apparatus for processing the fly ash includes a hopper for receiving the fly ash, a conveyor and a modified conditioner in which the fly ash is hydrated.
