摘要：

We introduce a simulated annealing algorithm for wavefront control to focus light through highly scattering media. Using 4096 independently controlled segments of modulated light, the intensity at the target is 125 times enhanced over the original intensity at a predefined target. The simulated annealing algorithm and existing phase control algorithms of focusing through scattering media are compared in detail experimentally. It is found that the simulated annealing algorithm achieves the highest enhancement with less time compared to a genetic algorithm. Published by ALP Publishing.
