近年来，人们对多种光束，如高斯光束、贝塞尔－高斯光束、拉盖尔－高斯光束

In recent years, people have conducted in-depth studies on the light intensity scintillation produced by a variety of beams, such as Gaussian beams, Bessel-Gaussian beams, Laguerre-Gaussian beams, Gaussian vortex beams, etc. when propagating in the atmospheric flow. Theoretical analysis has obtained the scintillation coefficient of the beam after the turbulence, and some conclusions have been drawn. For example, the scintillation coefficient will increase with the increase of the turbulence intensity, and will also increase with the increase of the transmission distance. The flicker coefficient is also different under the environment. However, this is only a theoretical analysis, how to measure the flicker coefficient in the laboratory is a very meaningful work. This section will briefly introduce the scintillation coefficient of light in the turbulent atmosphere theoretically, focusing on an experimental system for measuring the scintillation coefficient based on a spatial light modulator, and compare and analyze the measurement results.

近年来，人们对多种光束，如高斯光束、贝塞尔－高斯光束、拉盖尔－高斯光束、高斯涡旋光束等在大气揣流中传输时产生的光强闪烁进行了深入研究，通过理论分析得到了光束经过湍流之后的闪烁系数，得出了一些结论，如闪烁系数会随着湍流强度的增加而变大，也会随着传输距离的增加而变大，不同的光束在相同的环境下闪烁系数也不同等。然而这仅仅是理论分析，如何在实验室中测量出闪烁系数是一项非常有意义的工作。本节将从理论上简要介绍光在湍流大气中的闪烁系数，重点介绍一个基于空间光调制器的闪烁系数测量实验系统，并对测量结果进行对比分析

In recent years, many kinds of beams, such as Gaussian beam, Bessel Gaussian beam, Laguerre Gaussian beam, Gaussian vortex beam and so on, have been deeply studied. Through theoretical analysis, the scintillation coefficient of the beam after turbulent flow is obtained, and some conclusions are drawn, such as the scintillation coefficient will increase with the increase of turbulence intensity The scintillation coefficients of different beams in the same environment are also different. However, this is only a theoretical analysis, how to measure the scintillation coefficient in the laboratory is a very meaningful work. In this section, the scintillation coefficient of light in turbulent atmosphere is briefly introduced in theory, and a scintillation coefficient measurement experimental system based on spatial light modulator is mainly introduced, and the measurement results are compared and analyzed
