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 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.

摘要： Apparatuses, systems, and methods are presented for calibrating an inspection system, particularly a Laser Bond Inspection (LBI) system that identifies a strength of a test structure. The disclosed calibration system comprises a calibration panel, a surface motion sensor, and a processing circuit. The surface motion sensor senses a compression wave generated in the calibration panel responsive to a laser pulse applied by a LBI head to the calibration panel. The processing circuit outputs a calibration result for the laser inspection system responsive to one or more characteristics of the sensed compression wave. The calibration system provides significantly faster calibration results, and thus may be implemented more frequently to improve the accuracy and repeatability of the inspection system.

摘要： Described herein is a system for processing a workpiece that includes a plurality of lasers that each produces a laser beam pulse. The system also includes a laser control module that sequences temporal characteristics of the laser beam pulses. Additionally, the system includes a laser beam compensation module that shapes a near field intensity profile of at least one of the laser beam pulses and adjusts a path length of at least one of the laser beam pulses. The system also includes at least one laser beam position element that combines the laser beam pulses to produce a combined laser beam pulse at a surface of the workpiece.

摘要： A method for creation of a non-destructive inspection (NDI) standard employs a coupon of bonded layers or a composite structure having a predetermined thickness. A predetermined pulse width is defined. The coupon and a laser source are positioned with respect to one another and the laser source is used to create a laser pulse having the predetermined pulse width to create a disbond or delamination in the bond layer at a predetermined location. The coupon may then be used as a standard for calibration of NDI inspection tools by scanning the coupon with the tool to provide an inspection output. The output is then examined to confirm that the disbond or delamination in the coupon is properly identified in the output.
