The measurement of plasma-facing materials’ topography variation by means of temporal phase-shifting speckle interferometry technique

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...
