Abstract: A system is provided for facilitating the use of an in-motion slit radiographic technique to inspect 3-dimensional composite materials. The system includes a lead lined device that is adjustable to form various slit shaped and size openings. When used in conjunction with a standard X-ray source and film, the device prevents the non-parallel and undesirable portion of the X-ray radiation from creating a distorted image when complex 3-dimensional structures are inspected.

Abstract: A probe is disclosed for the nondestructive inspection of the interior walls of cylindrical recesses, comprising an elongated shaft having an ultrasonic transducer mounted thereon a predetermined distance from the longitudinal axis of the shaft and oriented for directing the axis of radiation of ultrasonic energy emanating from the transducer outwardly in a plane perpendicular to the longitudinal axis of the shaft. In another embodiment, the probe comprises a shaft having a lateral extension whereon a first ultrasonic transducer is mounted at a predetermined distance from the longitudinal axis of the shaft and is oriented for directing the axis of radiation of ultrasonic energy emanating therefrom parallel to a line formed by the intersection of planes perpendicular to the longitudinal axes of the shaft and lateral extension.
