Title: | Parameter-free optimization algorithm for iterative wavefront shaping | Authors: | Zhao, Q Woo, CM Li, H Zhong, T Yu, Z Lai, P |
Issue Date: | 15-Jun-2021 | Source: | Optics letters, 15 June 2021, v. 46, no. 12, p. 2880-2883 | Abstract: | Optical focusing through scattering media has a significant impact on optical applications in biological tissues. Recently, iterative wavefront shaping (WFS) has been successfully used to focus light through or inside scattering media, and various heuristic algorithms have been introduced to improve the performance. While these results are encouraging, more efforts are needed to tune parameters towards robust and optimum optimization. Moreover, optimal parameters might differ for different scattering samples and experimental conditions. In this Letter, we propose a "smart"parameter-free algorithm by combining a traditional genetic algorithm with a bat algorithm, and the mutation rate can be automatically calculated through real-time feedback. Using this method in iterative WFS, one can achieve robust and optimum performance without a parameter tuning process. | Publisher: | Optical Society of America | Journal: | Optics letters | ISSN: | 0146-9592 | EISSN: | 1539-4794 | DOI: | 10.1364/OL.427215 | Rights: | Journal©2021 Optical Society of America ©2021 Optica Publishing Group.
