Patent number: 10561404Abstract: Disclosed is a calibration system and method for a phased array ultrasound pipe inspection system, in which reliable calibration is obtained for notches at all angles using only a small number of notches for the calibration. The method comprises a one-time normalization step and a system calibration step which may be performed at regular intervals. Ultrasound transmission is in a single diverging beam for each aperture, while reception is selective for multiple well-defined reception angles. During the normalization step, plots of maximum response vs reception angle are plotted for each notch, and a normalization curve is constructed by fitting the maxima of these plots. The normalization curve is used to derive calibration targets at specific reception angles for specific calibration notches, which are then used for the system calibrations.Type: GrantFiled: June 2, 2017Date of Patent: February 18, 2020Assignee: Olympus Scientific Solutions Americas Inc.Inventors: Benoit Lepage, Guillaume Painchaud-April, Christophe Imbert, Charles Grimard

The wedge is machined to match a test surface to be inspected and is configured to shape the acoustic module so that the active surface of the acoustic module is parallel to the test surface. Different wedges may be machined to match different test surfaces, but the same flexible probe array assembly may be used for all such surfaces.Type: GrantFiled: May 23, 2017Date of Patent: February 18, 2020Assignee: Olympus Scientific Solutions Americas Inc.Inventors: Nicolas Badeau, Jason Habermehl

Publication number: 20200049670Abstract: 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.Type: ApplicationFiled: October 18, 2019Publication date: February 13, 2020Applicant: Olympus Scientific Solutions Americas Inc.Inventor: Benoit Lepage

Publication number: 20200018593Abstract: Disclosed is a system and method for ultrasonic measurement of the average diameter and roundness profile of a tube. A roundness algorithm represents the angular dependence of the tube surface profile as a sum of Fourier components, each component being a harmonic representing an integer number of undulations per revolution, with “0” (the first harmonic) corresponds to an average circle associated with the tube outer surface. A calibration block is used to calibrate the first harmonic, representing the average tube diameter.Type: ApplicationFiled: July 12, 2018Publication date: January 16, 2020Applicants: Olympus Scientific Solutions Americas Inc., Cudd Pressure Control, Inc.Inventors: Jinchi Zhang, James David Glascock

Publication number: 20200018594Abstract: Disclosed is a system and method for ultrasonic measurement of the average diameter and surface profile of a tube. A calibration block is used to calibrate the average tube diameter, and a correction is applied to account for any temperature difference of the couplant between calibration and test measurements. By using a linear probe, or a single probe with a finely pitched helicoidal scan, errors in diameter measurement due to presence of surface pits may be compensated.Type: ApplicationFiled: July 12, 2018Publication date: January 16, 2020Applicant: Olympus Scientific Solutions Americas Inc.Inventors: Jinchi Zhang, Nicolas Badeau

Patent number: 10309934Abstract: 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.Type: GrantFiled: March 29, 2017Date of Patent: June 4, 2019Assignee: OLYMPUS SCIENTIFIC SOLUTIONS AMERICAS INCInventors: Cécile Brütt, Guillaume Painchaud-April, Chi-Hang Kwan, Benoit Lepage
