中文摘要：

研究了采用高阶厄米高斯模激光进行空间微小平移测量的灵敏度极限，研究表明高阶模（TEMn0模）测量灵敏度极限为基模的√2n＋1倍。文章给出了一种基于高阶厄米高斯模的空间微小平移多象限探测方案，并结合实验参数对探测方案进行了分析，结果表明此方案是一种测量微小平移的简便而有效的方案。

英文摘要：

The sensitivity limit for spatial small displacement detection based on high-order Hermite-Gauss modes laser beam has been investigated, showing that the sensitivity limit for high-order mode （TEMn0 mode）is √2n＋1 times that of the fundamental mode. We also provide a kind of array detection scheme based on high-order Hermite-Gauss modes. With the practical parameters,numerical simulation of this detection scheme proves that our detection scheme is simple and effective for laser small displacement measurement,
