    摘要： A method of measuring a crystallographic orientation of an object using an ultrasonic transducer and a detector array including a plurality of ultrasonic detectors includes: determining a minimum distance between the transducer and the detector of the detector array closest to the transducer; placing the transducer and the detector array in contact with a surface of the object such that the transducer and the detector of the detector array closest to the transducer are separated by at least the minimum distance; using the transducer to generate an ultrasonic surface wave pulse in the surface of the object, the ultrasonic surface wave pulse having a pulse duration and including a longitudinal surface wave and a Rayleigh wave; and measuring a time of flight of a surface wave generated by the transducer between the transducer and each detector of the array to determine the crystallographic orientation of the object.

    摘要： Methods and systems for detecting a plume of a first fluid in a second fluid using an acoustic wave are provided, where the first fluid has a different acoustic index of refraction than the second fluid. A horizontal array having a plurality of receiving elements receives an acoustic signal propagated through the second fluid and at least one refracted signal refracted by the first fluid. The acoustic signal and the at least one refracted signal form a received signal. An interference pattern is detected from the received signal over the plurality of receiving elements. The interference pattern is due to interference between the acoustic signal and the at least one refracted signal. A horizontal angle of refraction is determined between the acoustic signal and the at least one refracted signal from the interference pattern. The horizontal angle of refraction is indicative of a physical characteristic of the first fluid.

    摘要： A method of modeling a surface of an object using ultrasonic transducers mounted on the surface by: providing a model of the surface comprising a primary set of surface points indicative of the height of the surface, transmitting pulsed waves from a first transducer to one or more second transducers along respective paths along the surface, measuring travel times of the pulsed waves along each path, calculating travel times based on the model of the surface, adjusting the model of the surface in response to any discrepancies between the measured travel times and the calculated travel times. The above steps are repeated until the discrepancies are smaller than a predetermined threshold. The step of calculating the travel times comprises interpolating the primary set of surface points in order to obtain an expanded secondary set of surface points, and the travel times are calculated using the expanded set.

    摘要： A system and method for evaluating a part-under-test (120) is disclosed. The part-under-test (120) is excited using at least one drive frequency. A first surface acoustical wave (SAW) mode (206) is identified in the frequency response (200). A separate reference peak (204) for the identified SAW mode (206) is also identified in the frequency response (200). At least one degeneracy assessment zone (208) is evaluated for existence of a surface defect trigger condition. If a surface defect trigger condition exists, the part-under-test (120) may be rejected. Otherwise, the part-under-test (120) may be accepted.

    摘要： An ultrasonic testing apparatus for a pipe end portion, which enables accurate ultrasonic testing, comprises an ultrasonic probe disposed under the pipe end portion. The probe 1 transmits ultrasonic waves to the pipe end portion and receives the ultrasonic waves therefrom. A probe holder houses the probe which is disposed under the pipe end portion to face the pipe end portion and follows the pipe rotation. The probe holder comprises a coupling medium reserver part that surrounds a space between the probe and the pipe end portion to contain a coupling medium therein and comprises a coupling medium reserver part body into which the coupling medium is supplied. An annular bellows part, which communicates with the reserver part body, can expand and contract vertically and an annular spacer, which is attached to the upper side of the bellows part and an upper surface thereof has a flat horizontal surface.

    摘要： A method of modelling a surface (3) of an object (2) using ultrasonic transducers (4, 5) mounted on the surface comprises the steps of: providing a model of the surface, the model comprising a primary set of surface points indicative of the height of the surface, transmitting pulsed waves from a first transducer (4) to one or more second transducers (5), the first transducer and each second transducer defining a respective path along the surface, measuring travel times of the pulsed waves along each path, calculating travel times based on the model of the surface, adjusting the model of the surface in response to any discrepancies between the measured travel times and the calculated travel times, and repeating the steps of transmitting, measuring, calculating and adjusting until the discrepancies are smaller than a predetermined threshold. The step of calculating the travel times comprises the sub-step of interpolating the primary set of surface points in order to obtain an expanded secondary set of surface points, the travel times being calculated using the expanded set. Thus the number of surface points to be determined is substantially reduced.
