Matrix arrays

High resolution transducers

1

Applications

Inspection of thick parts, forged parts, complex interface parts and difficult materials (coarse grain, non homogeneous).

Principle & Advantages

The shaping of the active surface in a 2D array allows a 3D beam steering and 3D correction of the focus, which can compensate, for example, for the defocusing effect of a complex interface or an anisotropic material.
Furthermore, matrix immersion transducers, like annular arrays, allow electronic focusing at different depths.

General Characteristics

  • Frequency from 300 kHz to 20 MHz
  • Number of elements: from 32 to 1024
  • High sensitivity and signal-to-noise ratio, thanks to the acoustic matching to water allowing a very good transfer of acoustic energy
  • Good axial resolution, and reduction of the unseen area below the surface thanks to a short pulse length
  • High reliability over time thanks to a design that is watertight and resistant to corrosion, compatible with permanent immersion under 1 m of water

Time Reversal Mirror Technique

Matrix arrays can be used with time reversal mirror technique (M Fink).
This patented technique using two successive shots allows significant signal to noise ratio improvements by compensating the material anisotropy.
