Linear phased array probes

Electronic beam scanning

Principle

Electronic scanning is combined with electronic focusing.
- Wide inter-element pitch allows a large scanning width.
- Focusing depth can be electronically selected.

Typical use in immersion
Possible use in contact or with water jet
Typical use in pulse-echo or in transmission (2 probes)

Applications

All applications where a mechanical scanning axis can be replaced by an electronic scanning axis, as for example :
- Plates, billet inspection
- Wheel, disk inspection by the lateral side

Advantages

- Inspection speed (set-up, scanning)
- Mechanical set-up simplification
