Abstract: A system and method for evaluating a bond is provided. The system uses an underwater spark discharge to generate a compression wave in a first vessel containing a liquid. The system further includes a second vessel in which a vacuum is pulled to hold the first vessel against a bonded structure being inspected. The compression wave is directed to propagate from the liquid into the bonded structure to apply a known force to the bond being inspected.

Abstract: A method for real-time surface imperfection detection for additive manufacturing and 3-D printing parts is provided. The method includes directing a first light radiation using one or more illumination sources, wherein the first light radiation illuminates a target area of a part being manufactured in a uniform chromatic light such that the target area appears to have a substantially uniform monochromatic color; capturing a current image of a second light radiation that is scattered or reflected by the target area using one or more feedback cameras; and analyzing the current image of the second light radiation using at least one of the one or more feedback camera with a previously acquired image to determine whether a surface imperfection exists or does not exist.

Abstract: Disclosed herein is an x-ray backscatter apparatus (“apparatus”) for non-destructive inspection of an object. The apparatus includes an x-ray emitter that includes a vacuum tube, an x-ray shield enclosed within the vacuum tube. The x-ray shield includes at least one emission aperture. The apparatus also includes a cathode enclosed within the vacuum tube and that is operable to generate an electron stream. Also included is an anode, enclosed within the vacuum tube and located relative to the cathode, to receive the electron stream and convert the electron stream from the cathode to an x-ray stream, and located relative to the emission aperture to direct at least a portion of the x-ray stream through the at least one emission aperture. Also disclosed are a system and a method that utilize the apparatus.

Abstract: Disclosed herein is a system and method for inspecting a bonded structure in a component. The system includes an integrated probe and a processor coupled to the integrated probe. The integrated probe includes an ultrasonic component and a laser component. The ultrasonic component is configured to transmit pulsed sound waves into the bonded structure and receive reflected pulsed sound waves from the bonded structure. The laser component is configured to generate laser pulses and direct the laser pulses to the bonded structure to generate tension waves across the bonded structure. The processor is configured to test a bonded structure in the component. Further, the processor includes a pre-test module configured to operate the ultrasonic component in a pre-test mode, a test module configured to operate the laser component in a test mode, and a post-test module configured to operate the ultrasonic component in a post-test mode.

Abstract: An x-ray source for a backscatter imager can include a first electron beam (e-beam) emitter for emitting a first e-beam and at least a second e-beam emitter for emitting at least a second e-beam. The first and second e-beam emitters can be powered by a at least one power supply, and can be configured to direct the first e-beam and the second e-beam toward an anode. An interaction of the anode with the first and second e-beams produces x-rays. The x-ray source is configured to output an amount of x-rays equivalent to a conventional x-ray source that includes a single e-beam emitter. However, because the x-ray source uses at least two e-beam emitters and a single anode, the power source required to power the e-beam emitters can operate at a lower wattage than a conventional power source powering the single e-beam emitter. The x-ray source is thus lighter in weight and outputs less radiation than conventional systems with a comparable x-ray output.

Abstract: A method of detecting porosity at and near a composite surface is disclosed, including projecting polarized light on a surface of a composite component and filtering out light reflected off of the surface. The method further includes imaging light scattered from inhomogeneities in the composite component, and generating a map of absence of composite material near the composite surface based on scatter intensity detected in the imaging step.

Abstract: The present disclosure provides for Non-Destructive Inspection of craft operating in high-atmosphere or outer space, by positioning a scintillating detector array leeward to a structural element of the craft relative to the Sun; collecting, by the detector array while the craft is in flight, solar radiation passing through the structural element; and outputting a radiographic image based on the solar radiation collected to an image analyzer. The image analyzer may composite several images taken over a period of time or decomposite images of intervening structural elements from the radiographic images. Automated alerts for non-conformances between the radiographic images and earlier-taken or architectural images are provided to users.
