标题： Detecting momentum weak value: Shack-Hartmann versus a weak measurement wavefront sensor

摘要： 波前传感的任务是测量光学场的相位。 这里，我们演示了广泛使用的Shack-Hartmann波前传感器检测横向动量的弱值，通常通过量子弱测量的方法来实现这一目标。 我们将输入状态扩展到部分相干态，并将其与弱测量波前传感器进行比较，后者具有更高的空间分辨率但动态范围较小。 由于弱值常用于研究基础量子物理和量子计量学，我们的工作将在这些领域找到重要的应用。 显示英文摘要

摘要： The task of wavefront sensing is to measure the phase of the optical field. Here, we demonstrate that the widely used Shack-Hartmann wavefront sensor detects the weak value of transverse momentum, usually achieved by the method of quantum weak measurement. We extend its input states to partially coherent states and compare it with the weak measurement wavefront sensor, which has a higher spatial resolution but a smaller dynamic range. Since weak values are commonly used in investigating fundamental quantum physics and quantum metrology, our work would find essential applications in these fields.
