Abstract: Methods are presented. Signals are sent into a first surface of a structure using an ultrasonic transducer. Ultrasound response signals are received at the ultrasonic transducer. A portion of a second surface of the structure is heated while the ultrasonic transducer is sending signals into the first surface, wherein the second surface is on an opposite side of the structure from the first surface. Infrared images of the portion of the second surface of the structure are taken after heating the second surface.

Abstract: A system and method for nondestructive inspection of a unitized composite structures is provided. The system includes an infrared thermographic camera and a carriage that can be mounted on, for example, adjacent frames of the unitized composite structure. The carriage can move along the length of the frames while the infrared thermographic camera collects and analyzes thermographic images of the frame, skin, and stiffeners. The carriage can be moved to other frames and the inspection continued until the entire unitized composite structure has be inspected.

Abstract: Methods for thermographic inspection of structures are disclosed. An example method includes positioning at least one of a heat source or a camera in a cavity defined by a first side of a structure of an aircraft and positioning the other one of the heat source or the camera at a second side of the structure opposite the first side; applying heat to the least one of the first side or the second side of the structure; measuring thermal energy emitted from the other one of the first side or the second side opposite the heat source; and identifying a defect or inclusion of the structure based on the measured thermal energy.

Abstract: A system for the detection of foreign object debris material on a surface of a composite part being manufactured. A platform is configured to move over the surface. A thermal excitation source is fixed to the platform and configured to direct infrared radiation across the surface. An infrared camera is also fixed to the platform and configured to scan the surface as the platform moves over the surface to detect and output a signal proportional to infrared radiation emitted by the surface and/or by any foreign object debris material on the surface in response to the infrared radiation from the excitation source. A controller is coupled to the excitation source and to the infrared camera and is configured to compare the signal from the infrared camera with a first predetermined threshold signal to detect if any foreign object debris material is located on the surface.

Abstract: A vehicle examination system includes an axle inspection system that is configured to inspect an axle of a vehicle. The axle inspection system includes an ultrasound scanning assembly, and an axle coupler that retains the ultrasound scanning assembly. The axle coupler is configured to moveably secure the ultrasound scanning assembly to the axle. An axle inspection control unit is in communication with the ultrasound scanning assembly. The axle inspection control unit is configured to control the ultrasound scanning assembly to ultrasonically scan the axle for anomalies as the vehicle moves.

Abstract: An optical scanning assembly for use in inspecting a channel is provided. The assembly includes a housing and an inspection probe that selectively advances from the housing along an axis. The probe includes a light source that directs light towards at least one side wall of the channel and a light detector that receives the light reflected from the side wall. The assembly further includes a controller in communication with the inspection probe. The controller obtains a first optical length measurement for the light reflected from the side wall when the inspection probe is in a first position along the axis within the channel, obtain a second optical length measurement for the light reflected from the side wall when the inspection probe is in a second position along the axis within the channel, and compare the first and second optical length measurements to determine variations in a geometry of the channel.

Abstract: A system for nondestructive evaluation of railroad rails, includes a carriage including a plurality of wheels movably supporting the carriage on the rails, a source of vibration mounted on the carriage and connected to transmit vibrations of a preselected frequency to test regions on the rails through the wheels to cause an increase in temperature of the rails at locations of flaws in the test regions, an infrared detector for recording thermal images of the test regions to detect the increase in temperature of the location of the flaws, a controller connected to actuate the infrared detector to record the thermal images of the vibrations impacting the test regions, and store the thermal images recorded by the infrared detector.
