摘要: A method of detecting local material changes in a composite structure is presented. A pulsed laser beam is directed towards the composite structure comprised of a number of composite materials. Wide-band ultrasonic signals are formed in the composite structure when radiation of the pulsed laser beam is absorbed by the composite structure. The wide-band ultrasonic signals are detected to form data. The data is processed to identify a local frequency value for the composite structure. The local frequency value is used to determine if local material changes are present in the number of composite materials.

摘要: A method for testing a structure using laser ultrasound includes steps of: (1) directing positioning light on a surface of the structure; (2) determining a spatial location and a spatial orientation of the surface from an evaluation of the positioning light reflected back from the surface; (3) directing pump light onto the surface to generate ultrasonic waves in the structure; (4) selectively locating a probe-light focal point of probe light on the surface, based on the spatial location determined for the surface; (5) selectively angularly orienting the probe light normal to the surface, based on the spatial orientation determined for the surface; and (6) directing the probe light onto the surface to detect a response to the ultrasonic waves.

摘要: A nondestructive bond strength testing method, including: coupling an expendable device to a structure under test, the expendable device including a patterned planar array of exploding bridge wires; simultaneously vaporizing the patterned planar array of exploding bridge wires by applying a pulse of electrical energy to the patterned planar array of exploding bridge wires; and sensing an initial disbonding signature of the structure under test.

摘要: Described herein is an apparatus, for shielding light generated by a laser during non-destructive inspection of an object. The apparatus includes a light shield at least partially enveloping the laser and defining a first opening through which light generated by the laser passes from the laser to the object. The light shield is opaque and includes at least one first biasing mechanism. The apparatus also includes at least one first light seal coupled to the light shield about the first opening of the light shield. The at least one first biasing mechanism is configured to urge resilient deformation of the at least one first light seal against the object. When the at least one first light seal is resiliently deformed against the object, light generated by the laser is constrained within a light containment space defined between the light shield, the at least one first light seal, and the object.

摘要: A method of detecting inconsistencies in a composite structure is presented. A pulsed laser beam is directed towards the composite structure comprised of a number of composite materials. Wide-band ultrasonic signals are formed in the composite structure when radiation of the pulsed laser beam is absorbed by a surface of the composite structure. The wide-band ultrasonic signals are detected over a duration of time to form data. The data comprises an ultrasonic A-scan spectrum. The data is processed to identify a structure signal in a frequency domain of the ultrasonic A-scan spectrum. The structure signal of the ultrasonic A-scan spectrum is compared to a structure signal of a composite structure standard to determine whether the inconsistencies are present in the number of composite materials.
