摘要：Temporal phase-shifting speckle interferometry is proposed to measure plasma-facing materials' (PFMs) topography variation in tokamak. In this approach, laser ablation method is used to simulate erosion and redeposition, and polished molybdenum/tungsten (Mo/W) samples which are related to PFMs have been tested. The geometric topography of the ablated area was reconstructed successfully via a numerical model developed in this work. The results demonstrate the feasibility of temporal phase-shifting speckle interferometry applied to topography measurement of PFMs. (C) 2017 Published by Elsevier Ltd.
