摘要:
A rapid image-based method for validating good electrical contact between existing LSP material on a structure, and LSP material on an applied patch, thus ensuring continuous LSP through the patch. The method and apparatus are used in the repair of LSP by validating an electrical connection between new and existing LSP materials. It can also be used during manufacturing to ensure good contact between sections of LSP material.

A system and methods for x-ray backscatter reverse engineering of structures. One embodiment includes a plurality of articulated arms attached to a movable base. Another embodiment includes a single counterweighted arm attached to a movable base. The arms include x-ray detectors. At least one x-ray source, which may be mounted on the arm(s), emits x-rays, which are backscattered off the surfaces and objects of interest and captured by the detectors to generate images of hidden objects. The present system provides improved speed and resolution over prior art systems. The system has a field-of-view and effective scanning range versatile enough to work in various orientations and in environments of various sizes. In certain embodiments the system is compact and lightweight so that it can be easily transported and used within confined spaces or in environments where weight is a consideration, such as inside or underneath aircraft. The system is also pointable and adaptable.

Methods and systems are disclosed for drilling counter sink fastener holes in composite materials with conductive foil lightning strike protection systems. Initially a non-destructive depth detector is scanned over a prospective fastener hole location. Then the depth of a conductive foil below a surface is detected. When the detected depth is less than a predetermined depth, a signal that indicates that a countersink fastener hole may be drilled is output. When the detected depth is greater than a predetermined depth, a signal that indicates that a countersink fastener hole may not be drilled is output.

For inspecting a structure with non-destructive x-ray inspection, probes are magnetically coupled to opposing surfaces of the structure. An inspection device may be autonomous with a feedback-controlled motor and/or a positional encoder. An inspection device may include wireless operation for at least one probe. A display may be included to provide real-time visual images from an x-ray detector or an optical imager.

A non-destructive inspection device has an infrared sensor for infrared thermography inspection of a structure or surface. A rotatable reflector reflects infrared light from an inspected surface to an infrared sensor. An inspecting portion of a non-destructive device is magnetically coupled to an actuating portion of the device for concerted movement of the portions. An inspection device includes both an infrared sensor for infrared imaging and an optical device such as a camera for visible light imaging.
摘要:
A method and apparatus for inspection of an object. The apparatus comprises an array of light sources and a support structure. The array of light sources is configured to generate beams of coherent light with a substantially uniform distribution of the beams of coherent light in an area on a surface of an object in the area that results in a number of speckle patterns in light reflected from the surface of the object in the area in response to the beams of coherent light in the area. The support structure is associated with the array of light sources.

The different advantageous embodiments provide a method and apparatus for generating an x-ray beam. The x-ray beam is generated using an x-ray tube. The x-ray tube and a power supply are located inside of a housing connected to a moveable platform. A rotatable wheel connected to the moveable platform is rotated while the x-ray beam is being generated. The rotatable wheel has a number of apertures that allows at least a portion of the x-ray beam to pass through the rotatable wheel as the rotatable wheel rotates.

摘要:
A detection method and indicator are disclosed that includes quantum dots that fluoresce under illumination of a first light having a first wavelength to indicate the presence of a predetermined condition, and in particular, a corrosion condition. The quantum dots are surrounded by a shell material that under normal conditions reflect the first light and reacts in the presence of the predetermined condition to permit the first light to illuminate the quantum dot to excite the quantum dot to emit a second light having a second wavelength, which when detected, indicates the presence of the predetermined condition.
