- 光通过散射介质聚焦是光通信和生物成像领域的重要目标。由于散射介质材料的密度分布具有高度非均匀性,相干光在非均匀介质中传输会经历多次散射。寻找与散射介质相匹配的入射光波前分布是解决这一问题的核心和关键。采用蚁群算法来优化入射光波前的相位分布。利用探测器测量介质后的焦点光强,发现蚁群算法获得的增强因子比传统的遗传算法高。数值仿真和实验验证了蚁群算法的可行性和稳定性。因此,今后在相干光通过散射介质聚焦与成像领域,应当优先考虑利用蚁群算法优化入射光的波前相位分布。
- Abstract:
- Focusing light through scattering media is an important goal in optical communication and bioimaging.Since the components of the scattering mediumare highly heterogeneous, light transport in such media experiences multiple scattering. A very challenging problem in such a process is to find the right wave front of the incident light. In this paper, an ant colony algorithm is exploited to optimize the phase distribution of the incident wavefront. It is found that the enhancement of the focus obtained by the ant colony algorithm is higher than the focus obtained by the genetic algorithm.The accuracy and stability of the ant colony algorithm are verified using both numerical simulation and experiment.Therefore, in the study of light focusing or imaging, the ant colony algorithm should be considered first.
