贝塞尔光束在湍流大气中传输的实验研究

Bessel Beams in Turbulent Atmosphere in the Experimental Study of Transmission

高斯光束通过螺旋相位板和轴棱锥可获得高阶贝塞尔光束。在实验室模拟大气湍流并研究了贝塞尔光束在湍流大气中的传输特性。着重讨论了湍流扰动强弱及拓扑荷数变化对贝塞尔光束传输特性的影响。实验表明,湍流强弱及拓扑荷数变化都会影响贝塞尔光束的传输,大气湍流会降低贝塞尔光束的相干性。

Gaussian beams passing through spiral phase plate and high-order Bessel beam axis pyramid available. In the laboratory simulation of atmospheric turbulence and to study the Bessel beam in the transmission characteristics of the turbulent atmosphere. Focused on the strength of turbulence and topological charge perturbation changes in the number of Bessel beam propagation properties. Experiments show that turbulence intensity and the number of topological charge change will affect the Bessel beam transmission, atmospheric turbulence will reduce the Bessel beam coherence.
