我们讨论了近场干涉仪中的物质波实验，并重点讨论了由于惯性力引起的失相现象。它们的存在可能导致所观察到的干涉对比度的显著降低，即使它们不会导致真正的退相干。我们提供了最重要的影响的定量估计，并通过实验证明了声振动的强烈影响。由于惯性力的影响对于更大质量粒子的干涉测量变得越来越重要，因此必须在未来的实验中识别和补偿惯性力。值此赫伯特瓦尔特70岁生日之际，我们谨以此文献给他。早在十多年前，赫伯特·瓦尔特就引发了一场关于干涉实验互补性的讨论，这场讨论至今仍有意义。
We discuss matter wave experiments in a near-field interferometer and focus on dephasing phenomena that are due to inertial forces. Their presence may result in a significant reduction of the observed interference contrast, even though they do not lead to genuine decoherence. We provide quantitative estimates for the most important effects and demonstrate experimentally the strong influence of acoustic vibrations. Since the effects of inertial forces become increasingly important for interferometry with more massive particles, they have to be identified and compensated for in future experiments. We dedicate this article to Herbert Walther on the occasion of his 70th birthday. Already more than a decade ago, Herbert Walther inspired a discussion on complementarity in interference experiments that is still of relevance today.
