摘要： A system includes at least one optical fiber having at least one FBG and a detection system. The optical fiber is configured to be coupled to a structure in at least one location. The location at which the optical fiber is to be coupled to the structure is different from a location at which the FBG is disposed. The detection system includes a light source configured to inject light into the optical fiber, a photodetector configured to detect a shift in a wavelength spectrum of light reflected by the FBG as a result of a time-varying strain induced at the at least one FBG, and a processor configured to detect a shear-horizontal guided stress wave propagating in said structure based on the shift in the wavelength spectrum detected by the photodetector induced by a longitudinal-type guided stress wave that is propagated along the optical fiber.

摘要： A system for non-destructive inspection of a structure includes a magnetostrictive pulser coil and a ferromagnetic strip. The ferromagnetic strip is coupled to the structure adjacent to the pulser coil. A scanner receiver probe is located adjacent to the ferromagnetic strip. The probe includes a probe body, a position encoder, and a magnetostrictive partial loading receiver coil. A magnet applies a biasing magnetic field to the ferromagnetic strip. A pulser system generates a time-varying current in the pulser coil to induce a time-varying magnetization in the ferromagnetic strip to generate guided wave energy in the structure. The probe detects reflected guided wave energy as the probe is moved around the circumference of the structure. A processor controls the pulser system, records guided wave reflections, and process the guided wave and probe position data to generate a one-dimensional image or a two-dimensional image of anomalies in said structure.

摘要： A method for ultrasonic guided wave defect detection in a structure is disclosed. The method includes driving a plurality of transducers to cause guided waves to be transmitted in the structure in a predetermined direction or focused at a predetermined focal point, receiving at least one reflected guided wave signal, and generating image data of the structure based on the at least one reflected guided wave signal. Processed image data are generated by performing at least one of baseline image subtraction or image suppression on the image data, and a location of at least one possible defect in the structure is identified based on the processed image data.

摘要： Non-destructive inspection systems (10) and methods for inspecting structural flaws that may be in a structure (15) based on guided wave thermography. The method may include sweeping a frequency-phase space to maximize ultrasonic energy distribution across the structure while minimizing input energy, e.g., via a plurality of actuators. The system may include transducer elements (12, 14, 16, 17) configured to predominantly generate shear horizontal-type guided waves in the structure to maximize thermal response from any flaws.
