分析了整体倾斜像差去除前后大气湍流畸变波前相位的功率谱。在激光实际大气水平传输实验中 ,利用 6 1单元自适应光学系统的哈特曼波前传感器 ,测量和分析了大气湍流畸变波前相位的功率谱。还建立了一种根据实际测量的波前相位功率谱数据估测自适应光学系统变形镜需要控制带宽大小和大气湍流格林伍德 (Greenwood)频率的方法。
The power spectrum of the wavefront phase of atmospheric turbulence before and after the global tilt aberration removal is analyzed. In the experiment of laser actual atmospheric level transmission, the power spectrum of the wavefront phase of atmospheric turbulence distortion was measured and analyzed by Hartmann wavefront sensor of 6 1-unit adaptive optics system. A method of estimating the bandwidth of the adaptive optics deformable mirror and the Greenwood frequency of atmospheric turbulence based on the actual measured wavefront phase power spectrum data was also established.
