Abstract: Disclosed herein is an x-ray backscatter apparatus for non-destructive inspection of a part. The x-ray backscatter apparatus includes an x-ray source and an x-ray collimator. The x-ray collimator includes a plurality of emission apertures and a detection aperture. The x-ray backscatter apparatus further includes an x-ray intensity sensor that is fixed to the x-ray collimator over the detection aperture such that at least a portion of an uncollimated x-ray emission, collimated into the detection aperture, is detected by the x-ray intensity sensor. The x-ray backscatter apparatus additionally includes an emission alignment adjuster that is operable to adjust a position of the uncollimated x-ray emission relative to the plurality of emission apertures and the detection aperture in response to the at least the portion of the uncollimated x-ray emission detected by the x-ray intensity sensor.

Abstract: A system and method for determining a width of a gap in a structure 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 the structure. The compression wave is directed to propagate from the liquid into the structure and is detected after it propagates through the structure including the gap.

Abstract: A method of manufacturing a prepreg composition includes disposing a plurality of core/shell quantum dots on or in a resin matrix of the prepreg composition. The quantum dots may include an inner core that when excited by light of a first wavelength emits a detectable luminescent signal, and an outer shell that blocks light of the first wavelength from reaching the inner core when the outer shell is intact. A method of determining the suitability of a pre-impregnated composite fiber material for incorporation into a composite structure and a method of detecting damage to a prepreg composition due to ultraviolet radiation exposure utilizing the core/shell quantum dots are provided.

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: A method of monitoring a thermal protection system coupled to a structural component is provided. The thermal protection system includes a thermally insulative body and at least one layer of thermochromatic material applied thereon such that the at least one layer is positioned between the thermally insulative body and the structural component. The method includes determining a value of a thermochromatic property of the at least one layer of thermochromatic material, wherein the value of the thermochromatic property is responsive to an amount of heat applied to the at least one layer of thermochromatic material, comparing the value to a baseline value of the thermochromatic property, and determining degradation of the thermal protection system when the value of the thermochromatic property deviates from the baseline value.

Abstract: A method includes exciting, at a first time period, a first set of pixels in an excitation array, wherein the first set of pixels comprises more than one pixel, and no pixel in the first set of pixels is adjacent to another pixel in the first set of pixels. The method also includes exciting, at a second time period, a second set of pixels in the excitation array wherein the second set of pixels comprises more than one pixel, and no pixel in the second set of pixels is adjacent to another pixel in the second set of pixels. The method retrieves excitation data, wherein the excitation data is comprised of data from the first set of pixels and data from the second set of pixels, and the excitation data is capable of being combined to reconstruct an image of a target object for rendering on a display.
