论文摘要
我们在弯曲的时空中存在轴心磁场的情况下，呈现出几何光学元件的简明推导。每当可以通过几何光学（Eikonal近似）描述光时，与情况没有轴承场的唯一区别是可观的双折射现象。因此，基于传播光线的红移和距离估计值以及重力透镜引起的剪切和放大率不受光与轴突场的相互作用的影响。
We present a concise derivation of geometric optics in the presence of axionic fields in a curved space-time. Whenever light can be described via geometric optics (the eikonal approximation), the only difference to the situation without axionic field is the phenomenon of achromatic birefringence. Consequently, redshift of light and distance estimates based on propagating light rays, as well as shear and magnification due to gravitational lensing are not affected by the interaction of light with an axionic field.
