论文摘要
检测死区和由光偏移引起的标题误差是光学泵送标量磁力测定法的两个重要问题。我们引入了基于原子方向的单光束磁力计方案，以使用偏振化和路径弯曲的Herriott空腔同时解决这些问题。在这里，将反射镜插入腔中，以弯曲中间的光路，并将它们分为两个分离的正交区域，以避免检测死区。此外，在每个光学区域的中心中添加半波板，因此每次通过波板时，光偏振都会翻转，并且光移效应在空间上平均。该操作被证明可以消除AC光移动引起的未注意到的标题误差。本文开发的方法可使用，并且易于在其他原子设备中应用。
Detection dead zones and heading errors induced by light shifts are two important problems in optically pumped scalar magnetometry. We introduce an atomic orientation based single-beam magnetometry scheme to simultaneously solve these problems, using a polarization-reversing and path-bending Herriott cavity. Here, a reflection mirror is inserted into the cavity to bend the optical paths in the middle, and divide them into two separated orthogonal regions to avoid the detection dead zone. Moreover, half-wave plates are added in the center of each optical region, so that the light polarization is flipped each time it passes the wave plates and the light shift effects are spatially averaged out. This operation is demonstrated to eliminate the unnoticed heading errors induced by ac light shifts. The methods developed in this paper are robust to use, and easy to be applied in other atomic devices.
