Because of the unlimited range of state space, orbital angular momentum (OAM) as a new degree of freedom of light has attracted great attention in optical communication field. Recently there are a number of researches applying deep learning on recognition of OAM modes through atmospheric turbulence. However, there are several limitations in previou...

... shown in Fig. 5. (a), MDCNN is perfectly capable of sorting LG light with positive and negative TC with the same absolute value. As the absolute value of TC grows, the accuracy drops gradually. We believe this is because the crosstalk induced by atmospheric turbulence between channels gets severer as the absolute value of TC grows, as shown in Fig.4 (b) ...

In this paper, the propagation properties of a vortex cosh-Gaussian beam (vChGB) in turbulent atmosphere are investigated. Based on the extended Huygens–Fresnel diffraction integral and the Rytov method, the analytical expression for the average intensity of the vChGB propagating in the atmospheric turbulence is derived. The effects of the turbulen...
In this study, we propose a scheme to capture the amplitude and phase profile of the orbital angular momentum (OAM) beam based on coherent detection. In the scheme, the OAM beam to be measured is interfered with a local plain wave which is prepared at the receiver, and two charge-coupled devices (CCDs) are used to record the constructive and destru...
The propagation of General Model vortex Higher-order cosh-Gaussian beam (GMvHchGB) in maritime atmospheric turbulence has been studied analytically by the extended Huygens-Fresnel principle. Based on the derived formula, we performed numerical simulations to study the impact of maritime atmospheric turbulence on the properties of this beam under va...
In this study, the effects of roadside building roof shapes and roadside tree plantings on the dispersion of vehicle exhaust gas pollution in the urban street have been carefully explored. Three typical roof shapes, i.e., flat, triangle and round shapes, are considered in the present work. Firstly, the numerical simulations of air pollution transpo...
