从傅里叶变换光学的相关理论出发，提出了一种适合提高平行发射方式下的相干合成效率的方法。并依据激光光学的知识，通过数值模拟计算该方法对激光相干合成效率的影响。以平行发射系统和透镜系统作参考，发现对各光束赋初始相位的方法可以提高平行发射系统的合成效率，并且其极限值为对应透镜系统的合成效率。不同的赋初始相位值对合成效率的影响结果各不相同，通过对比，找到了最好的赋初始相位值方案。

Based on Fourier transform optics, a method to improve coherent combination efficiency in parallel transmission system is introduced. According to the knowledge of laser optics, the influence of the method on laser coherent combination efficiency is calculated by numerical value simulation. Numerical simulation of the parallel transmission system and the lens system shows that the method described in the passage indeed improve the effi-ciency, with limitation that equals the efficiency in lens system. Different initial phase schemes lead to different ef-fect, and the best scheme is got by comparing.
