Virtual phased array examples

Tube inspection example

In line testing of tubes requires high acoustic performances and high inspection speed

Thanks to the electronic rotation of the beam, circular phased array probes allow very fast inspection
Besides, phased array probe made with Imasonic's piezocomposite technology provide high resolution and signal to noise ratio.

Main features

Combination of electronic scanning, focusing and deflection
Circular pre-focusing of the array probe
Use of 1, 2 or 4 simultaneous beams, depending on the setup
Virtual rotation speed up to 10000 rpm
Instantaneous electronic adaptation to tube diameter and thickness
No rotating probe holder required

Conventional weld inspection with single angled transducers required 2 perpendicular scanlines

Only one mechanical scanline is necessary thanks to the electronic translation of the beam.
Imasonic phased array probes allow beam deflection untill the required beam angle while keeping the necessary sensitivity due to the low cross coupling between elements.

Main features

Combination of electronic scanning, focusing and deflection
Only one mechanical scanline required instead of two
Adapted Focusing for each shot and acoustic path
Faster inspection
