Uni-index variable angle ultrasonic phased array probe

technical field [0001] The present invention relates to an ultrasonic probe in the form of a transducer array, and more particularly to an ultrasonic probe having a probe body having a geometry such that the transducers in the transducer array are within a distance from the origin in the probe body are equidistant, so sound waves produced simultaneously by two or more transducers in the array arrive at the origin at the same time. Background technique [0002] Ultrasonic probes are used to inspect workpieces in industrial applications. Such inspections have been performed by the contact method, where the probe is brought into intimate contact with the workpiece, but coupled to the workpiece using a couplant such as glycerin or oil, or by non-contact or immersion methods, where a column of water is positioned between the workpiece and the transducer between. [0003] The probe includes a delay body, and at least one transducer mounted on the delay body. The at least one tr...
