Abstract: A method of thermographic inspection is disclosed, including applying a thermal pulse to a surface and capturing an image of a thermal response of the surface. The image is captured with an infrared camera through a polarizer having a first orientation. The method further includes determining, by analysis of the image, whether the thermal response is indicative of a crack on the surface.

Abstract: A method, apparatus, and system for generating images. An imaging system comprises a computer system with a controller. The controller is configured to receive from a shearography camera system an unloaded visible light image generated of a coating in an area of a structure while the area is in an unloaded state and a loaded visible light image generated while the area is in a loaded state and receive from an infrared camera system an unloaded thermal image generated while the area is in the unloaded state and a loaded thermal image generated while the area is in the loaded state. The controller is configured to subtract the loaded visible light image from the unloaded visible light image to form a subtracted visible light image. The controller is configured to subtract the loaded thermal image from the unloaded thermal image to form a subtracted thermal image.

Abstract: Disclosed herein is a method of measuring an effectiveness of an ultraviolet coating. The method comprises irradiating the UV coating with UV energy comprising a predetermined spectrum of wavelengths. The method also comprises measuring an intensity of the UV energy reflected from the UV coating. The method further comprises comparing a measured intensity of the UV energy reflected from the UV coating with a previously measured intensity of the UV energy reflected from the UV coating to obtain comparison data. The method additionally comprises determining, in response to the comparison data, the effectiveness of the UV coating.

Abstract: A system and method for determining the strength of a bond joining a composite structure is provided. The system includes a gas gun produces a short gas pulse directed normal to a surface of the composite structure and that creates a compression wave through the composite structure; a monochromatic x-ray system produces a monochromatic x-ray that is incident at an angle to the surface and that passes through the composite structure; a scintillator screen receives transmitted x-rays that pass through the composite structure; a mirror receives and magnifies radiation emitted from the scintillator screen; a detector receives the radiation from the scintillator screen; an electronic processor configured to process the radiation detected by the detector; and a synchronization controller configured to synchronize operation of the gas gun, the monochromatic x-ray system, and the detector.

Abstract: An x-ray backscattering imaging system creating a backscatter image representing a structure is disclosed. The system includes a drum rotatable about an axis of rotation at a rotational speed, a radioactive source, a container, at least one collimator, at least one light emitting element, and a plurality of backscatter detectors. The radioactive source is connected to the drum and generates x-ray beams. The container houses the radioactive source and is constructed of a material that substantially blocks the x-ray beams generated by the radioactive source. The collimator is defined by the container and has a length and an aperture, where the collimator filters a stream of x-rays generated by the radioactive source such that the x-ray beams traveling substantially parallel with respect to the length of the collimator pass through the aperture. The light emitting element generates visible light and is positioned to direct the visible light into the collimator.

Abstract: Disclosed herein is a scintillator for use in an x-ray backscattering system. The scintillator comprises an inorganic scintillator portion made of inorganic scintillating material and comprising one or more inorganic material elements. Each inorganic material element of the one or more inorganic material elements comprises an outer surface, and an inner surface opposite the outer surface. The outer surface is configured to be proximate to a subject to be scanned, such that the outer surface is configured to receive x-ray photons scattered by the subject. The scintillator also comprises an organic scintillator portion made of an organic scintillating material and comprising a front surface. At least a portion of the front surface abuts the inner surface of at least one of the one or more inorganic material elements.

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.
