提出了一种基于变形镜薄膜反射镜和模拟退火算法相结合的可编程光束整形方法。该算法迭代地调整37个独立电极的控制电压，以减少所选形状和实际波束形状之间的差异。实验结果表明，该系统能够自适应地创建，按需，高斯和超高斯光束轮廓，密切匹配所需的目标参数。
We present a programmable beam-shaping method based on the combination of a deformable mirror membrane mirror and a simulated annealing algorithm. The algorithm iteratively adjusts the control voltages of 37 independent electrodes to reduce the variance between the chosen shape and the actual beam shape. The experimental results show that the system is capable of adaptively creating, on demand, Gaussian and super-Gaussian beam profiles that closely match the desired target parameters.
