ABSTRACT:
A test apparatus for testing objects such as tubing is disclosed. The apparatus includes a rotatively fixed transducer and a rotating lens, wherein the transducer receives an input signal and converts it into an emitted wave energy, the lens focuses the emitted wave energy onto the tubing and focuses reflected wave energy from the tubing back onto the transducer, and the transducer receives the reflected wave energy and converts it into an output signal. The transducer can be provided on one support shell and the lens can be provided on another support shell. One of the support shells can then be positioned within the other support shell. The apparatus is useful for performing dimensional tests and longitudinal and circumferential flaw tests on tubing.
