Abstract: Techniques for reducing or eliminating cross talk in row-column addressed array (RCA) probes are described. A diode can be connected in series to piezo-composite element in each pixel of the RCA to prevent cross talk. A resistor can also be provided in parallel to the piezo-composite element for discharging purposes and providing DC paths for the forward and backward bias voltages to the diodes. Thus. RCA probes using the techniques disclosed herein can use sub-apertures for, among other things, inspecting longitudinal and transverse flaws, and for more efficient local focusing for an acoustic camera without significant cross talk interference.

Abstract: Acoustic data, such as a full matrix capture (FMC) matrix, can be reconstructed by applying a previously trained decoder machine learning model to one or more encoded acoustic images, such as the TFM image(s), to generate reconstructed acoustic data. A processor can use the reconstructed acoustic data, such as an FMC matrix, to recreate new encoded acoustic images, such as TFM image(s), using different generation parameters (e.g., acoustic velocity, part thickness, acoustic mode, etc.).

Abstract: Acoustic evaluation of a target can be performed using an array of electro-acoustic transducers. For example. a technique for such evaluation can include generating acoustic transmission events using different transmitting apertures, the apertures defined by corresponding zones along the array, the zones including multiple electro-acoustic transducer elements. In response to the respective acoustic transmission events. respective acoustic echo signals are received. Representations of the respective received acoustic echo signals are coherently summed. The coherently summing includes applying determined nominal element delay factors to the respective representations to approximate a virtual probe normal to a nominal shape of a surface of a structure being inspected. A pixel or voxel value is corresponding to a specified spatial location within the structure being inspected is generated using the coherently summed representations.

Abstract: Non-destructive testing of an elongate object can include using an adaptable apparatus to support objects having different cross-sectional profiles. For example, an adaptable inspection fixture can support inspection probes for acoustic or eddy current inspection, as illustrative examples. Generally, the apparatus comprises opposing portions which are pivotable and connected by a linkage to maintain the opposing portions in a specified orientation relative to each other while permitting independent rotational orientations of each respective opposing portion such as to accommodate test objects. For example, the opposing portions can be substantially parallel across multiple configurations. Optionally, the apparatus can maintain a specified orientation of one or more radius probes with respect to an object under test.

Abstract: Acoustic inspection productivity can be enhanced using techniques to perform compression of acquired acoustic data, such as data corresponding to elementary A-scan or other time-series representations of received acoustic echo data. In various approaches described herein, time-series data can be decimated for efficient storage or transmission. A representation of the time-series data can be reconstructed, such as by using a Fourier transform-based up-sampling technique or a convolutional interpolation filter, as illustrative examples. The techniques described herein can be used for a variety of different acoustic measurement techniques that involve acquisition of time-series data (e.g., A-Scan data). Such techniques include Full Matrix Capture (FMC) applications, plane wave imaging (PWI), or PAUT, as illustrative examples.

Abstract: Using various techniques, a position of a probe assembly of a non-destructive inspection system, such as a phase array ultrasonic testing (PAUT) system, can be determined using the acoustic capability of the probe assembly and an inertial measurement unit (IMU) sensor, e.g., including a gyroscope and an accelerometer, without relying on a complex encoding mechanism. The IMU sensor can provide an estimate of a current location of the probe assembly, which can be confirmed by the probe assembly, using an acoustic signal. In this manner, the data acquired from the IMU sensor and the probe assembly can be used in a complementary manner.

Abstract: A material profile can be determined by assuming an elliptical or circular arc geometry and by using acoustic noise generated by diffuse internal reflection and/or specular reflection on the internal (ID) or external (OD) interface of the material under inspection, such as a pipe or curved plate. A non-destructive testing (NDT) technique can acquire acoustic data of the material using an ultrasonic signal. The acquired acoustic data can be filtered such that the acoustic noise generated by diffuse internal reflection and/or specular reflection is separated from any flaws in the material. Positions of the acoustic noise can be determined and then a regression technique can be applied to the positions, which can generate an equation of a circle, for example, such as to provide a radius and thickness of the pipe or curved plate.

Abstract: An eddy current probe assembly for analyzing an article is provided. The eddy current probe assembly includes a housing, an eddy current probe disposed on or within the housing, and a barrier layer. The housing has a coolant passage that extends into the housing and forms a loop within the housing. The coolant passage allows for coolant flow through the housing. The eddy current probe thermally couples with a first portion of the coolant passage at a first surface of the eddy current probe. The barrier layer is on a second surface of the eddy current probe opposite the first surface of the eddy current probe.

Abstract: Techniques for compensating a TFM delay computation live (e.g., during acquisition) as a function of the measured thickness along the scan axis of a probe of an acoustic inspection system. At various scan positions, the acoustic inspection system can measure the thickness of the object under test. With the measured thickness, the acoustic inspection system can compute the delays used for the TFM computation to reflect the actual thickness at that particular scan position of the probe.
