摘要
针对有振幅调制和位相畸变的激光束通过空间滤波 像传递系统的传输进行了讨论 ,通过数值计算 ,分析了振幅调制和位相畸变大小对激光束传输的影响 。
The near-field propagation of laser beam with amplitude modulations and phase aberrations through spatial filtering-image relaying is discussed. In numerical simulation, the obtained results show that the distortions can lead to a significant increase of light intensity fluctuation in the near-field, optimized filtering pinhole can decrease the high frequency fluctuation light intensity.
