It was recently shown that pulsed ion accelerators can provide relatively deep and uniform implantation profiles required to improve tribological properties of steels. However, due to the collective effects generated by the accelerated ion flux, a strong and fast heating process is produced in a very short time. As a result, an important thermal effect is added to the pure implantation process which induces irreversible residual deformations. In this work the quantitative analysis of the correlation fringes is carried out through the evaluation of the optical phase distribution using a phase-shifting method. Then, the continuous phase map is obtained using an iterative unwrapping algorithm and the residual deformations are finally determined.
