Data entry for logging of measurements can be automated through the use of an analysis of one or more bitmap images, such as included in a video stream. For example, a mechanical measurement instrument such as a digital thickness gauge can include a display that is placed in the field of view of a digital image sensor. One or more measurement values can be extracted from corresponding bitmap images from a captured video stream, such as in an automated manner in response to a stability criterion being met or in response to another triggering operation. An extracted measurement value can be automatically logged, such as provided to another application, or captured on an electronic form in an appropriate field, such as having an appropriate scale or unit of measure. Such an approach facilitates automation of measurement logging for instruments lacking any wired or wireless networking capability.

Disclosed is an electronic system for resetting the voltage of a charge-sensitive pre-amplifier having input from an X-ray detector and output to an ADC. The pre-amplifier gain is increased so that the RMS ADC noise is less than 1% of a representative digitized X-ray signal. The reset logic is configured to avoid loss of X-ray counts and to prevent the pre-amplifier output being outside the allowable input range of the ADC. Reset is initiated when the pre-amplifier output rises above an upper level, which is below the maximum allowable ADC input. Reset is also initiated when a pile-up event is detected, provided that such reset will not cause the pre-amplifier output to fall below the minimum allowable ADC input. At each reset a known amount of charge is removed from the pre-amplifier, and the reset time is continuously adjusted to ensure that the charge amount does not drift.

Adaptive total focusing method (TFM) such as for zero-degree acoustic inspection
A full matrix capture (FMC) acoustic acquisition technique can be modified in a manner to compensate for one or more of variation from a nominal distance between an acoustic transducer array and the structure being scanned, or a variation from a nominal angle (e.g., inclination or declination) of the array surface with respect to the structure being scanned. Such modification can include determining incremental delay factors to be added or removed from nominal delay values in A-Scan data based on offset values corresponding to the transmit and receive transducer elements (or apertures) used for acquiring a particular A-Scan instance. The compensated A-Scan data in the FMC acquisition can then be used TFM imaging, for example.

Ultrasonic inspection configuration with beam overlap verification
Disclosed is a beam overlap verification system and method for phased array ultrasonic inspection. A scan plan for the ultrasonic inspection defines a suitable probe, wedge and calibration block having machined defects for the geometry to be inspected, and makes a beam definition which defines a set of ultrasonic beams emitted by the phased array. An intersection amplitude unit records the response amplitudes from each defect at predetermined intersection points of adjacent beam pairs as the probe and wedge are manually scanned across the calibration block. An overlap verification module determines the −6 dB overlap of all adjacent beam pairs which are relevant to the geometry to be inspected, and verifies that the beam overlap conforms to the required coverage according to the ASME or other relevant codes. In this way, coverage is experimentally verified during calibration prior to inspection of a known geometry, such as a weld.

Disclosed is an ultrasonic non-destructive testing and inspection system and method for determining acoustic velocities in a test object. Beams of acoustic energy from firing an element of an emitting probe propagate in a first wedge, and a beam incident at the critical angle generates a surface wave in the test object. The surface wave propagates to a second wedge and signals are received at receiving elements of a receiving probe array. When a set of appropriate delays is applied to the receiving elements, the acoustic time-of-flight is the same to all receiving elements. Determination of the appropriate delays and the times-of-flight for P-type surface waves and Rayleigh surface waves enables computation of the P- and S-wave acoustic velocities in the test object. The time-of-flight measurement also enables computation of the separation between the first and second wedges.
Disclosed is an apparatus and method for generating virtual inspection channels mid-way between the physical inspection channels of an eddy current array probe, thereby reducing the coverage loss and improving defect sizing and imaging. The method is based upon a calibration to determine the mid-channel coverage loss for parallel defects having their long axis parallel to the scanning direction. Based on the coverage loss measurement, a vector analysis system is constructed enabling generation of virtual channel signals which are available for processing in the same way as physical channels, with impedance plane representation including real and/or imaginary signal components. The system differentiates between parallel and perpendicular defects and employs different algorithms to generate virtual channel signals for parallel and perpendicular defect orientations.

Disclosed is an apparatus and method for TFM post-processing of a FMC or HMC matrix acquired with an ultrasonic array probe. Post-processing is performed by calculating TFM beam forming amplitudes using round-trip delays to a focal point lying at depth d on a line at angle θ within the test object. Based on the beam forming amplitudes over a range of values of d within the imaging volume, a calculated A-scan is derived, which is equivalent to the response A-scan produced in conventional phased array imaging, but has the advantage of being focused at all points along the line. By post-calculation of calculated A-scans over a range of angles θ within the imaging volume, an imaging method is derived which is readily adapted to existing codes based on conventional A-scan imaging.

Disclosed is a composite focusing wedge for ultrasonic non-destructive testing/inspection. The composite wedge comprises a base made of machined or cast material, and a lens made of a material which is cast in liquid form and subsequently solidifies. The acoustic velocity in the base material is less than that in the lens material. The castable lens material conforms exactly to a convex machined or cast surface of the base, thereby forming a concave lower surface of the lens. A flat ultrasonic probe is coupled to a planar upper surface of the lens. The minimum distance between the lower concave and upper planar surfaces of the lens is less than one acoustic wavelength in the lens material. The ringdown time of reverberations between the two surfaces is then sufficiently short that there is no interference between the reverberations and signals from sub-surface flaws in the object being tested.

Probe holder providing constant lift-off for in-line bar-pipe testing
Disclosed is a probe holder for in-line inspection of the surface of bars of high value alloys. To attain full coverage of the inspected surface, the bar is rotated while either the bar or the probe holder is translated. The probe holder of the invention ensures constant probe lift-off by allowing the probe to move freely under its own weight, while constraining the motion to be only in the radial direction of the bar. The lift-off distance is defined by a spacer which is made of soft material to avoid damaging the inspected surface. Although the spacer is soft, its wear due to friction with the rotating bar is minimized by minimizing the pressure between the spacer and the bar. This is achieved by resting most of the mechanism weight on two rollers, with only the much smaller weight of the probe resting on the spacer.
