计算结果表明，相位不连续点的数目不仅与描述光强起伏量的大气湍流强度、传输路径长度和传输光的波长有关，而且还与湍流的内尺度有关。
The structure and character of deformable mirror were analyzed , and the conflict between the deformation band and the pitch of deformable cells was pointed out . the " two - time compensation " wave - front correct mode was introduced to settle that conflict . the method for allocating wave - front aberration and designing static corrector was found , and the " two - time compensation " wave - front correct mode was validated by simulation
分析了变形镜的结构特点，初步给出了变形镜本身驱动单元数与校正量之间的制约关系；引入“二次补偿”波前校正方案，解决了变形镜校正量有限与高功率固体激光系统波前误差起伏量大的矛盾，建立了波前校正对象优化分配、静态校正器优化设计等细节过程所需要的方法，通过仿真模拟验证了“二次补偿”波前校正方案对于降低变形镜校正量要求和放宽光学元件加工精度的作用； 5
