用消衍射方法能改善列阵透镜的照明均匀性。本文详细研究了振幅型边缘软化，位相型边缘软化和硬边波纹光阑等技术在高功率激光靶面均匀照明技术中的应用。 Elimination of diffraction methods can improve the illumination uniformity of the array lens. In this paper, the application of amplitude edge-softening, phase-edge-edge softening and hard-edge corrugated aperture in the uniform illumination of high-power laser target has been studied in detail.
