SYSTEM AND A METHOD OF ADAPTIVE FOCUSING IN A PHASED ARRAY ULTRASONIC SYSTEM

摘要

Disclosed in the present disclosure is a phased array system configured to ultrasonically inspect test targets complex surfaces while employing the surface profiling capability of phased-array linear and sectorial scans. Adaptive focusing is employed for inspecting the test target by using customized apertures according to the surface profiles to generate a plurality of beams that are evenly and thoroughly spaced along a scan line inside the test target.

1. A phased array ultrasonic inspection system configured to inspect a test object having
a complex test surface, the system comprising:
a phased array probe configured to emit and receive ultrasonic signals from the test object,an ultrasonic signal acquisition unit receiving electronic echo signal data;a surface profile module configured to conduct at least one profiling routine to facilitate a set of profiling focal laws, analyze the corresponding echo signal data and define the geometric profile of the test surface;a programmable logical processor further comprising an adaptive focusing module configured to conduct at least one adaptive focusing routine to define at least one adaptively focused electronic scan which is partially defined by at least one center of at least one aperture of the probe according to the geometric profile,wherein the logical processor facilitates to inspect the test object by applying the defined electronic scan.
