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); and a 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).

A system for determining the cross sectional profile of an object having two opposed surfaces comprising: ultrasonic transducer means having a reference surface and arranged to emit and receive ultrasonic energy via said reference surface; thickness determining means connected to said transducer means for causing said transducer means to emit ultrasonic energy via said reference surface and for detecting reflected ultrasonic energy received by said transducer means via said reference surface in order to derive indications of the distance between said reference surface and an ultrasonic energy reflecting surface facing said reference surface; a carriage supporting said transducer means; guide means defining a linear travel path having a reference point and supporting said carriage for movement along said travel path; position determining means operatively associated with said carriage for deriving an indication of the location of said carriage along said travel path relative to said reference point; means for securing said guide means to the object so that the linear travel path extends along one of the two opposed surfaces; signal processing means coupled to said thickness determining means and said position determining means for producing representations of the distance between the opposed surfaces of the object correlated with the location of said carriage relative to said reference point when said reference surface is in contact with one of the two opposed surfaces; and a calibrating block carried by said means for securing at a location adjacent the object when said guide means are secured to the object, said calibrating block being disposed along said travel path to cooperate with said ultrasonic transducer means for allowing calibration of said thickness determining means.
