| 摘 要： | 用能随时改变镜面面形的能动反射镜控制并产生适于各种需要的焦斑形态。由于对焦斑形态的控制取决于能动反射镜对激光波前的拟合能力, 通过计算机仿真, 对能动反射镜在不同驱动器数量和排布方式时拟合给定波面(由几何变换法给出) 的能力进行了研究。计算结果表明, 采用自适应光学技术能在焦面上形成ICF 实验所需要的光斑形态。

| Abstract: | Laser beams profile at focal plane can be controlled using active mirror in ICF system because the beam's profile has strong relationship with the surface of active mirror, the surface of active mirror can be changed at any time and maintained for a long time. In this paper, the capabilities of fitting given wave front (computed by Geometric Transformation Method) at conditions of different actuator numbers and different arrangements have been investigated by computer simulation. The computing results present that the needed laser profile can obtained by adaptive optical technology. |

| Keywords: | controlling focal profile adaptive optics active mirror wave front fitting capability. |
