| 摘 要： | 给出了一种考虑光源的强度分布后用两个变形镜头实现场共轭的算法,并对高斯光束进行了数值模拟,结果表明这种算法是有效的。变形镜平滑的表面可以剔除相位局部跳变,明显改善光强分布。对高斯光束,发射面相位面形状十分简单,易于用变形镜构造。本文还讨论了两变形镜之间距离的影响,最后指出如何改进现有算法。

| Abstract: | We present an algorithm for producing conjugation field using two deformable mirrors. The algorithm is demonstrated effective by simulations using a Gaussian beam as the source. The simulations shows that the smooth surface of deformable mirrors eliminates the the local phase fluctuations on the first mirror, evidently improving the intensity pattern on the second mirror, and that for a Gaussian beam, the needed phase plane is very easy to be constructed by deformable mirrors. The effects of the distance between the mirrors is also discussed. Finally, we point out how to improve the present algorithm. |
