AUTOFOCUS

AUTOFOCUS Get the best image quality with a single click, no matter how complex the geometry is.



Auto-focusing algorithm, included in all SITAU models, simplifies the process of setting-up a phased-array inspection.



 

A fully automated process detects the surface profile of the part, calculates the focal laws and programs the equipment to get the best possible image. No matter how complex the geometry is, Auto-Focusing will set-up all parameters for you. It not only saves you time, but also allows you to face challenging inspections where the part geometry is not accurately known or changes during the scan.

Auto-focusing is a fully automated 2-step process, carried out in less than 1 second:

 

1 - Part geometry detection: Using a few emission events, the geometry of the part is detected and estimated.

 

2 - Focal-Law calculation: With our patented Virtual- Array method, dynamic focal laws are calculated for the whole image, giving the best resolution at all depths.

 

Typical applications:

 

• Water-tank immersion inspections.

• Irregular surface parts.

• Custom-developed wedges.

• Automated inspection of shape varying components.
