论文摘要
波前传感的任务是测量光场的相位。在这里，我们证明了广泛使用的Shack-Hartmann波前传感器检测到横向动量的弱值，通常是通过量子弱测量方法实现的。我们将其输入状态扩展到部分相干状态，并将其与弱测量波前传感器进行比较，该传感器具有较高的空间分辨率，但动态范围较小。由于弱值通常用于研究基本量子物理学和量子计量学，因此我们的工作将在这些领域中找到必要的应用。
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.
