| 摘 要： | 介绍了模拟自适应光学系统中受大气湍流影响的光学波前的四种方法,即基于Zernike多项式的K—L函数展开法、小波法、Fourier法以及ARMA法。分析比较了四种方法模拟精度和速度。结果表明,前两种方法不论是精度还是速度上都比较好,更适合湍流波前的模拟。

| Abstract: | In this paper four simulation methods used to simulate the optical wavefront distorted by atmospheric turbulence are provided, including Karhunen-Loeve function based on Zernike polynomials, wavelets transform, Fourier transform and ARMA method. And their precision and velocities are compared. As a result, the first two methods are better in precision and velocity and more suitable for the simulation of the turbulence wavefront. |
