摘要： An inspection system is provided to examine internal structures of a target material. This inspection system combines an ultrasonic inspection system and a thermographic inspection system. The thermographic inspection system is attached to ultrasonic inspection and modified to enable thermographic inspection of target materials at distances compatible with laser ultrasonic inspection. Quantitative information is obtained using depth infrared (IR) imaging on the target material. The IR imaging and laser-ultrasound results are combined and projected on a 3D projection of complex shape composites. The thermographic results complement the laser-ultrasound results and yield information about the target material's internal structure that is more complete and more reliable, especially when the target materials are thin composite parts.

摘要： The invention is directed to a laser ultrasound testing system with adaptive generation of sonic energy signals. The system may detect or test features of the manufactured object such as defects and layer properties. A laser generator initiates a sonic energy signal in a manufactured object. A measuring device measures the sonic energy signal. Then, a signal analyzer and/or a model processor determine if the signal is optimized. If the signal is not optimized, optimized operating characteristics of the laser generator are calculated. These optimized operating characteristics may include wavelength, beam dimension, temporal profile and power. Next, the laser generator initiates an improved sonic energy signal by utilizing the optimized operating characteristics. In this manner, more accurate testing and detection is achieved.

摘要： Ultrasonic testing techniques may involve the measurement of ultrasonic waves from the tested part. These waves may reflect from surfaces of various layers within the part. Further, these waves may reflect from faults, defects, voids, fractures, and others. As such, the measured ultrasonic wave is a complex mix of these reflections. One method for detecting flaws, defects, and others may be to express the signal in terms of a set of basis functions. These functions may be summed to produce the measured signal. Further, basis functions may be chosen such that a select set of the basis functions characterize the fault and/or defect. In one exemplary embodiment, the coefficients associated with the basis function may be non-zero when a defect is present. As such, a defect may be detected quickly and automatically.

摘要： Apparatus and method for detecting shear resonances includes structure and steps for applying a radiation pulse from a pulsed source of radiation to an object to generate elastic waves therein, optically detecting the elastic waves generated in the object, and analyzing the elastic waves optically detected in the object. These shear resonances, alone or in combination with other information, may be used in the present invention to improve thickness measurement accuracy and to determine geometrical, microstructural, and physical properties of the object. At least one shear resonance in the object is detected with the elastic waves optically detected in the object. Preferably, laser-ultrasound spectroscopy is utilized to detect the shear resonances.
