Abstract
An ultrasonic probe for examining an object with ultrasound and a corresponding examination method are provided. The probe includes a plurality of emitter elements able to emit ultrasonic waves for emitting a focused ultrasonic beam into the object through an active area of a surface of the object, and a profilometer for determining the profile of the surface of the object and for controlling the emission of the ultrasonic beam depending on the determined profile. The profilometer includes an image-taking apparatus for taking at least one digital image of the active area and an image processing module able to determine the profile of the active area by analyzing the optical blurring of the or at least one image.
Claims10
An ultrasonic probe for examining an object with ultrasound, the probe comprising:
- a plurality of emitter elements configured to emit ultrasonic waves for emitting a focused ultrasonic beam into the object through an active area of a surface of the object;
- a profilometer configured for determining the profile of the surface of the object and for controlling the emission of the ultrasonic beam depending on the determined profile, the profilometer including an image-taking apparatus configured for taking at least one digital image of the active area and an image processing module able to determine the profile of the active area by analyzing an optical blurring of the at least one image.
A method for non-destructive examination of an object having a surface, the method comprising:
- determining a profile of an active area of the surface by taking at least one digital image of the active area and analyzing the optical blurring of said at least one image by a profilometer;
- and
- emitting a focused ultrasonic beam into the object through the active area by a plurality of ultrasonic wave emitter elements, each ultrasonic wave emitter element being controlled depending on the determined profile.
