光束的旋转特性是由它的角动量控制的。它表明，光的轨道角动量（OAM）有一个强烈增强的旋转灵敏度时，与旋转的物体相互作用。拉盖尔-高斯（LG）模作为一种常用的OAM本征态，为测量物体的转动提供了方便的依据。然而，以往的研究大多集中在经典的旋转测量，很少有研究涉及到真实的结构物体的旋转的非局部传感。利用参量下转换产生的空间纠缠光子的全场量子关联，我们用具有径向和方位折射率的LG模来表示闲频臂中的旋转结构物体，发现信号光子的相移与闲频物体的角位移和信号光子的OAM数成正比.原理验证实验表明，使用更高的OAM可以非局部地提高物体的旋转角分辨率。我们的工作表明，潜在的应用在开发一个非接触的方式遥感旋转角度的任意对象，无论其旋转对称性。
The rotational properties of a light beam are controlled by its angular momentum. It has shown that light's orbital angular momentum(OAM) have a strongly enhanced rotational sensitivity when interacting with an rotating object. So, as a commonly used eigenstate of OAM, Laguerre-Gaussian(LG) modes provided a convenient basis for the measurement of rotation of the object. However, most previous study focus on the classical rotation measurement, few researches have paid attention on the nonlocal sensing of a real structured object's rotation. Here, by utilizing the full-field quantum correlations of spatially entangled photons generated by parametric down-conversion, we use LG modes with both radial and azimuthal indexes to represent the rotation structured object in idler arm and find that the phase shift of signal photons is proportional to both of the angular displacement of idler objects and measured OAM number of signal photons. The proof-of-principle experiment reveals that the object's rotation angular resolution may be nonlocally improved by using higher OAM. Our work suggests potential applications in developing a non-contact way for remotely sensing the rotation angle of an arbitrary object, regardless of their rotational symmetry.
