摘要： A material characteristic measurement approach measures an internal state of a material by measuring the nonlinear shift in velocity induced by different acoustic energies. The technology for implementing this measurement approach is relatively simple, robust, permits portable measurements, does not require that an unloaded initial condition of the material be measured or otherwise known in order to determine a characteristic of the material, can be applied using one or more transducers, and does not require physical contact with the material. Some example material characteristics include a residual stress existing without any external mechanical force applied, applied stress, a fatigue state, age, an interference-fit fastener stress, bio-activity, a nanostructure mixture of the material, a heat treatment of the material, a cross-linking of polymers in the material, a bio-growth organization of the material, a clotting factor of blood or blood-like material, a cure of an adhesive or sealant material, or the microstructure of the material.

摘要： A method of inspecting a rotatable shaft for the presence of defects may include continuously rotating a shaft under an applied load. As the shaft is rotated, an ultrasonic signal may be propagated along the length of the shaft. Attenuated or reflected ultrasonic signals may be collected from the shaft as the shaft is rotated. The presence of a defect in the shaft is determined by analyzing the collected ultrasonic signals.

摘要： A system and method of detecting acousto-photonic emissions in optically turbid media that provide increased levels of detection sensitivity. The detection system includes an ultrasonic transducer, a laser, a photo-detector for detecting ultrasound-modulated laser light, and circuitry for processing the detected signals for subsequent analysis. The ultrasonic transducer generates an ultrasonic wave that propagates within an optically turbid medium. The laser generates a coherent light beam, which is split to form signal and reference beams. The signal beam is sent through the turbid medium, where it is phase modulated by the ultrasound. The ultrasound-modulated signal beam is provided to a photo-refractive crystal for subsequent interference with the reference beam to convert the phase modulation to intensity modulation. The DC offset of the signal beam intensity provides a measure of the magnitude of the mean phase shift induced by the ultrasound on the multiply scattered optical field within the turbid medium.

摘要： A defect detection system for thermally imaging a structure that has been energized by sound energy. The system includes a transducer that couples a sound signal into the structure, where the sound signal causes defects in the structure to heat up. In one embodiment, a hard metal disk is positioned between the transducer and the structure to help couple the sound energy from the transducer into the structure. A predetermined force is applied to the transducer and a pulse duration and a pulse frequency of the sound signal are selected so that the sound energy induces acoustic chaos in the structure, thus generating increased thermal energy. A thermal imaging camera images the structure when it is heated by the sound signal.

摘要： An electromagnetic drive causes a cantilever of a probe-based instrument to deform flexurally by transmitting a high frequency AC signal through an electromagnetic actuator located in the vicinity of the cantilever. The AC signal preferably is an RF carrier signal having a frequency that is substantially higher than the resonant frequency of the cantilever. The carrier signal may, if desired, be modulated with a lower frequency modulation signal to induce the cantilever to oscillate, preferably at resonance. Alternatively, the carrier signal may be transmitted to the electromagnetic actuator without being modulated in order to deflect the cantilever quasi-statically. Cantilever response can then be monitored either directly in response to the imposition of the electromagnetically induced deformation of the cantilever in response to probe/sample interaction to obtain measurements regarding characteristics of the sample, the environment, and/or the cantilever.
