In optics, the rotation of a phase-space can be realized via light propagation through both an inhomogeneous medium with a radial gradient of refractive index and two special kinds of mirror-symmetrical optical systems suggested by Lohmann. Although light propagation through Lohmann's systems is described in terms of matrix optics, light propagation through the gradient-index medium is traditionally described as a solution of the wave equation. The difference in these descriptions hinders the understanding of the phase-space rotators. Fortunately, there is a matrix description of light propagation through a gradient-index medium too. A general description of the phase-space rotators is presented, which can be used to treat light propagation through both Lohmann's systems and the gradient-index medium in a unified matrix manner.
在光学中，相空间的旋转可以通过光在具有径向折射率梯度的非均匀介质以及由洛曼提出的两种特殊的镜对称光学系统中传播来实现。尽管光在洛曼系统中的传播是用矩阵光学来描述的，但光在梯度折射率介质中的传播传统上被描述为波动方程的解。这些描述方式的差异阻碍了对相空间旋转器的理解。幸运的是，也存在光在梯度折射率介质中传播的矩阵描述。本文给出了相空间旋转器的一般描述，它可以用于以统一的矩阵方式处理光在洛曼系统和梯度折射率介质中的传播。
