摘要： A system for inspecting a structure with coda acoustic waves, via a given surface (S) that is accessible from the exterior of the structure. The system operates to acoustically excite the structure at least one determined excitation point (Pe1) of the given surface (S) with an ultrasonic pulse of determined form, measure vibrations at least three set measurement points (Pmi) on the given surface (S), during a time window set with respect to the ultrasonic pulse, and exploit the vibration measurements in order to define an indication (Pd) in the structure of at least one possible defect using a coda acoustic-wave signal at each of the measurement points (Pmi).

摘要： Systems and methods are provided for ultrasonic imaging of composite parts. One embodiment is a method that includes providing an object having multiple layers of fibers and resin, inducing ultrasonic waves at locations along the object, and attenuating the ultrasonic waves at the regions due to regions interspersed among the layers that each exhibit an elastic modulus distinct from an elastic modulus of the fibers and distinct from an elastic modulus of the matrix. The method further includes receiving the attenuated ultrasonic waves, and analyzing the attenuated ultrasonic waves to determine depths of the regions.

摘要： Provided is a method and a system for multi-channel acoustic communication and sensing. For example, there is provided a system that includes a processor and a memory. The processor, when executing instructions from the memory, can perform certain operations. The operations can include classifying a motion detected near an ultrasonic receiver based on a Doppler shift observed in a signal measured by the ultrasonic receiver. The classifying can further include detecting a side lobe in a power spectrum of the signal to indicate that the motion has been detected.

摘要： A system and methods of nondestructive testing are described. The system includes an immersion ultrasonic probe and a laser vibrometer. The immersion ultrasonic probe and a sample are immersed in a fluid contained in an immersion tank and the laser vibrometer is disposed outside of the immersion tank. A tightly focused ultrasonic beam from the immersion ultrasonic probe and a laser beam from the laser vibrometer are both transmitted upon a sample, the laser beam being transmitted through the wall of the immersion tank. Since the ultrasonic beam is tightly focused and the laser beam samples only a small area impinged by the ultrasonic beam, microscopic resolution is obtained.

摘要： Methods, systems, devices, and products for ultrasonic borehole logging using an ultrasonic borehole imaging tool in a borehole intersecting the earth formation. Methods may include adjusting a focus for an ultrasonic beam generated from a single-transducer ultrasonic assembly of the ultrasonic imaging tool; using a receiver to generate measurement information responsive to an ultrasonic signal caused by the ultrasonic beam; and estimating a parameter of interest from the measurement information. Methods may include adjusting the focus in dependence upon environmental conditions, the environmental conditions comprising at least one of: i) standoff between the ultrasonic imaging tool and a wall of the borehole; and ii) borehole annulus conditions. Methods may include adjusting the focus in substantially real-time. The ultrasonic beam may be focused with a focal zone at the borehole wall configured to produce a beam spot size of a selected diameter.

摘要： Systems and methods are provided for performing OCT vibrography based on the synchronization of components of the OCT vibrography system. An A-scan trigger is employed to synchronize the operation of the scanning subsystem that scans the sample beam and an acoustic stimulus source that generates an acoustic stimulus for vibrographic measurements. The acoustic stimulus source is controlled such that when the scanning subsystem dwells on an imaging line selected for vibrography measurements, the acoustic stimulus is generated over a plurality of A-scans and the phase of the acoustic stimulus is locked to the A-scan trigger, such that the phase of the acoustic stimulus is incrementally modified with each A-scan. The accumulation of the acoustic phase is therefore synchronized to the A-scan trigger. The synchronization, providing synchronized acoustic phase evolution during each acoustic phase waveform cycle, permits the use of the OCT vibrography system for simultaneous anatomical and functional imaging.

摘要： A wafer chuck includes a support structure having a first side structurally configured to support a wafer, and a vacuum zone formed on the first side of the support structure. The vacuum zone may be at least partially bounded by a ring extending from a recessed surface of the first side of the support structure. The wafer chuck further includes a plurality of suction cups disposed in the vacuum zone, where one or more of the plurality of suction cups is coupled with a channel extending through the support structure. One or more vacuums are in fluid communication with the channel, where a vacuum is structurally configured to provide suction through the channel.
