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.
