关键的原子探针显微分析的完整性，断层重建是建立原子原子以下的一个简单的协议建立了前几代的仪器。在本文中，经过简短的审查的主要重建协议，我们描述了最近的改进，从使用精确的公式，使显着减少空间失真，特别是附近的边缘重建。我们还展示了如何重建参数的预测值可以从静电模拟，并最终引入参数变化的整个分析。(C)2010年爱思唯尔BM。All rights reserved.
Key to the integrity of atom probe microanalysis, the tomographic reconstruction is built atom by atom following a simplistic protocol established for previous generations of instruments. In this paper, after a short review of the main reconstruction protocols, we describe recent improvements originating from the use of exact formulae enabling significant reduction of spatial distortions, especially near the edges of the reconstruction. We also show how predictive values for the reconstruction parameters can be derived from electrostatic simulations, and finally introduce parameters varying throughout the analysis.
