    Abstract: 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.

    Abstract: Generally, in a non-destructive test application, a compressed representation of an acoustic echo signal acquired by a non-destructive test (NDT) probe assembly can be received, such as via a network. The compressed representation can include data indicative of changes in phase values of the acoustic echo signal. Using the compressed representation, a time-domain representation of an instantaneous phase signal can be constructed from the compressed representation. The constructed instantaneous phase signal can be used in constructing at least one of an uncompressed acoustic echo signal representation or an image. As an illustration, amplitude values of sampled acoustic echo signals can be suppressed in the compressed representation, reducing data volume associated with transmitting a representation of the acquired acoustic echo signal.

    Abstract: 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.
