在层析概率表示的框架内，我们引入了最近被证明携带轨道角动量的特定光学高斯态。我们得到了光的旋转高斯态的辛层析图和光学层析图，这些层析图唯一地定义了量子态和经典态。由于该方法在状态重建和测量中使用方便，因此需要开发并应用于上述状态。考虑到这一目的，我们得到了在纯差光学层析成像实验中可直接测量的振幅正交的平均值和方差。我们还考虑了旋转高斯态在层析图中的时间演化，得到了相应的层析传播算子。
Within the framework of the tomographic probability representation, we introduce specific optical Gaussian states, which were recently proved to carry the orbital angular momentum. We obtain the symplectic and optical tomograms defining uniquely both quantum and classical states for the rotating Gaussian states of light. This approach needs to be developed and applied to the mentioned states due to the convenience of using in the state reconstructions and measurements. Having in mind this aim, we obtain the mean values and variances of the amplitude quadratures directly measurable in the homodyne optical-tomography experiments. Also we consider the time evolution of the rotating Gaussian states in terms of the tomograms and obtain the corresponding tomographic propagator.
