摘要： A method and apparatus for three-dimensional visualization and analysis for automatic non-destructive examination of a solid Rotor using ultrasonic phased array is disclosed. Data is acquired by scanning a solid rotor with a phased array ultrasound transducer producing a plurality of two dimensional ultrasound scans. Each of a plurality of sample points of a plurality of two dimensional ultrasound scans are associated with a corresponding 3D image point of a regular grid. A kernel function for each of the plurality of sample points defining a size and shape of a kernel located at the corresponding image point is determined. A weight is assigned to each kernel which, in one embodiment, is based on the sample point value. A value for each image point of the regular 3D grid is determined based on kernels overlapping each image point. A three-dimensional volume representing the solid rotor is then visualized.

摘要： A system for determining the cross sectional profile of an object (24) having two opposed surfaces (26,28), includes:an ultrasonic transducer (16) having a reference surface (20) and arranged to emit and receive ultrasonic energy via the reference surface (20);a thickness determining unit (60) connected to the transducer (16) for causing the transducer (16) to emit ultrasonic energy via the reference surface (20) and for detecting reflected ultrasonic energy received by the transducer (16) via the reference surface (20) in order to derive indications of the distance between the reference surface (20) and an ultrasonic energy reflecting surface facing the reference surface (20);a carriage (2) supporting the transducer (16);a guide member (4) defining a linear travel path having a reference point and supporting the carriage (2) for movement along the travel path;a position determining unit (12,44,62) operatively associated with the carriage (2) for deriving an indication of the location of the carriage (2) along the travel path relative to the reference point;elements (32,34) for securing the guide member (4) to the object (24) so that the linear travel path extends along one of the two opposed surfaces (26); anda signal processing device (64) coupled to the thickness determining unit (60) and the position determining unit (12,44,62) for producing representations of the distance between the opposed surfaces (26,28) of the object (24) correlated with the location of the carriage (2) relative to the reference point when the reference surface (20) is in contact with one of the two opposed surfaces (26,28).

摘要： An inspection head where non-destructive inspection is structured to fit into narrow spaces, and to accurately and repeatably move an inspection probe along a surface to be inspected. Movement of the inspection head along an X, Y, Z, Θ, and Φ-axis is precisely controlled by individual drive mechanisms.
