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: Disclosed herein is an apparatus for electromagnetic x-ray control. The apparatus comprises a thermionic filament, positioned at a first end of a micro-focus x-ray tube and configured to generate an electron stream. The apparatus also comprises an x-ray generation target, positioned within the micro-focus x-ray tube at a second end of the micro-focus x-ray tube, opposite the first end, to receive the electron stream and to generate x-rays in response to the electron stream impinging on the x-ray generation target. The apparatus further comprises an electromagnetic field element, configured to generate an electromagnetic field that receives the electron stream and operable to vary the electromagnetic field to redirect the electron stream, within the micro-focus x-ray tube, to impinge on the x-ray generation target at variable locations on the x-ray generation target. Each one of the variable locations corresponds to a different one of multiple variations of the electromagnetic field.

Abstract: An example system for inspecting a surface includes a laser, an optical system, a gated camera, and a control system. The laser is configured to emit pulses of light, with respective wavelengths of the pulses of light varying over time. The optical system includes at least one optical element, and is configured to direct light emitted by the laser to points along a scan line one point at a time. The gated camera is configured to record a fluorescent response of the surface from light having each wavelength of a plurality of wavelengths at each point along the scan line. The control system is configured to control the gated camera such that an aperture of the gated camera is open during fluorescence of the surface but closed during exposure of the surface to light emitted by the laser.

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 that comprises a deposition head configured to deposit multiple tows in a stacked configuration one layer at a time. Each tow of the multiple tows is a currently-applied tow when the tow is a most-recently deposited tow of the multiple tows and a tow of the multiple tows is a covered tow when the tow is directly covered by the currently-applied tow. The system also comprises a probe head, configured to move along and be spatially offset from the currently-applied tow after deposition of the currently-applied tow. The probe head is further configured to transmit an incident microwave beam into the currently-applied tow as the probe head moves along the currently-applied tow. The incident microwave beam has a frequency low enough to pass entirely through the currently-applied tow and high enough to pass entirely through no more than the currently-applied tow and the covered tow.

Abstract: Various techniques are provided to utilize nanostructures for process monitoring and feedback control. In one example, a method includes forming a layer of material including nanostructures distributed therein. Each nanostructure includes a quantum dot and a shell encompassing the quantum dot. The shells and quantum dots are configured to emit a first and second wavelength, respectively, in response to an excitation signal. The method further includes applying the excitation signal to at least a portion of the layer of material. The method further includes detecting an emitted signal from the portion of the layer of material, where the emitted signal is provided by at least a subset of the nanostructures in response to the excitation signal. The method further includes determining whether a manufacturing characteristic has been satisfied based at least on a wavelength of the emitted signal. Related systems and products are also provided.
