Claim Text:
1. A hybrid inspection system comprising: a first probe comprising an air-coupled transducer configured to emit ultrasound signals and to air couple the ultrasonic signals into a workpiece, wherein the workpiece has opposed interior and exterior surfaces; and a second probe comprising a liquid coupled transducer configured to receive the ultrasonic signals emitted by the air-coupled transducer of the first probe via a liquid couplant between the liquid coupled transducer and the workpiece, wherein the air-coupled transducer of the first probe is a different type of transducer than the liquid-coupled transducer of the second probe, and wherein the first probe comprising the air-coupled transducer is configured to be positioned proximate the interior surface of the workpiece that has limited accessibility in that the interior surface of the workpiece is less accessible than the opposed exterior surface.
