    Abstract: A field deployable infrared imaging (FDIR) system for inspecting a composite component comprises an emitter configured to impart heat into a composite component via infrared radiation, a camera configured to capture an infrared image of the composite component, and a processing system configured to post-process the infrared image. A method of inspecting a composite component is disclosed that comprises subjecting a component to infrared radiation, capturing a thermal image of the component, inspecting the captured thermal image for defects in the composite component, and post-processing the thermal image using a second order derivative algorithm wherein the post-processed thermal image shows the defect better than the captured infrared image.

    Abstract: A system and method to inspect flaws associated with a part. The system includes a first image capturing device configured to capture a first set of images of the part and a computer operably associated with first image capturing device and configured to receive and analyze the first set of images. The method includes treating the part with a magnetic particle and fluorescent penetrant processing, capturing a first set of images of an outer surface of the part with the first image capturing device, and identifying a part defect with an algorithm associated with the computer.

    Abstract: A field deployable infrared imaging (FDIR) system and method for inspecting a composite component comprises a hand-held long-wave IR camera to capture a thermal image of the composite component, wherein the camera has an adjustable temperature control that captures an image with a 10 degree working range, a frame capture rate of at least 1 second for a length of time of not less than 90 seconds; and a processor for post-processing the thermal image using a second order derivative algorithm wherein the post-processed thermal image shows the defect better than the captured infrared image, and detects the one or more defects in the composite component.

    Abstract: One aspect of a process to inspect a composite component includes traversing multiple ultrasonic probe array portions on respective multiple component surfaces of the composite component. The multiple component surfaces are either separate from or at angles to each other. The process includes simultaneously passing an ultrasonic signal into the multiple component surfaces through the multiple ultrasonic probe array portions. The process also includes receiving a response to the ultrasonic signal through the multiple ultrasonic probe array portions.
