摘要： Examples of the present subject matter provide techniques for calculating amplitude fidelity (AF) for a variety of grid resolutions using a single TFM image of a specified flaw. Thus, the grid resolution may be set so that it yields a desired AF using a calculation process without performing a blind iterative process. Moreover, examples of the present subject matter may measure AF in more than one axis, improving accuracy.

摘要： Systems and methods are disclosed for conducting an ultrasonic-based inspection. The systems and methods perform operations comprising: receiving a plurality of scan plan parameters associated with generating an image of at least one flaw within a specimen based on acoustic echo data obtained using full matrix capture (FMC); applying the plurality of scan plan parameters to an acoustic model, the acoustic model configured to determine a two-way pressure response of a plurality of inspection modes based on specular reflection and diffraction phenomena; generating, by the acoustic model based on the plurality of scan plan parameters, an acoustic region of influence (AROI) comprising an acoustic amplitude sensitivity map for a first inspection mode amongst the plurality of inspection modes; and generating, for display, a first image comprising the AROI associated with the first inspection mode for capturing or inspecting the image of the at least one flaw.

摘要： An acoustic inspection system can be used to generate a surface profile of a component under inspection, and then can be used to perform the inspection on the component. The acoustic inspection system can obtain acoustic imaging data, e.g., FMC data, of the component. Then, the acoustic inspection system can apply a previously trained machine learning model to an encoded acoustic image, such as a TFM image, to generate a representation of the profile of one or more surfaces of the component. In this manner, no additional equipment is needed, which is more convenient and efficient than implementations that utilize additional components that are external to the acoustic inspection system.

摘要： A phase-based approach can be used for one or more of acquisition, storage, or subsequent analysis, e.g., A-scan reconstruction or Total Focusing Method imaging, in support of acoustic inspection. For example, binarization or other quantization technique can be used to compress a data volume associated with time-series signal acquisition. A representation of phase information from the time-series signal can be generated, such as by processing the binarized or otherwise quantized time-series signal. Using the representation of the phase information, a phase summation technique can be used to perform one or more of A-scan reconstruction, such as for pulse-echo A-scan inspection, or a TFM imaging technique can be used, as illustrative examples. In such a phase summation approach, time-series representations of phase data can be summed, such as where each time-series can be delayed (or phase rotated) by an appropriate delay value and then aggregated.

摘要： A compression technique can be used for processing or storage of acquired acoustic inspection data. For example, data indicative of peak values of an A-scan time-series can be stored to provide a compressed representation of such time-series data. A representation of the original A-scan data can be reconstructed, such as using the data indicative of the peak values, and a digital filter. Such an approach can dramatically reduce a volume of data associated an acoustic acquisition, such as a Full Matrix Capture (FMC) acquisition to be used for Total Focusing Method (TFM) beamforming and related imaging.

摘要： An acoustic technique can be used for performing non-destructive testing. For example, a method for acoustic evaluation of a target can include generating respective acoustic transmission events via selected transmitting ones of a plurality of electroacoustic transducers, and in response to the respective acoustic transmission events, receiving respective acoustic echo signals using other receiving ones of the plurality of electroacoustic transducers, and coherently summing representations of the respective received acoustic echo signals to generate a pixel or voxel value corresponding to a specified spatial location of the target. Such summation can include weighting contributions from the respective representations to suppress contributions from acoustic propagation paths outside a specified angular range with respect to a surface on or within the target, such as to provide an acoustic path-filtered total focusing method (PF-TFM).

摘要： Examples of the present subject matter provide a calibration technique to configure inspection parameters directly on an object. The calibration technique may include a target device configured to be placed on a testing surface of an object for calibration. The target device may reflect acoustic waves transmitted from a transducer probe. The reflected acoustic waves may then be used for determining one or more characteristics of the object.
