Real time polarization imaging of weld pool surface
Résumé
The search for an efficient on-line monitoring system focused on the real-time
analysis of arc welding quality is an active area of research. The topography and the
superficial temperature field of the weld pool can provide important information which can be
used to regulate the welding parameters for depositing consistent welds. One difficulty relies
on accessing this information despite the bright dazzling welding arc. In the present work,
Stokes polarimetry and associated shape-from-polarization methods are applied for the ...
