    Area of Science:

    • Optics and Photonics
    • Computational Science
    • Biophysics

    Background:

    • Light focusing through scattering media is crucial for applications in biological imaging and materials science.
    • Traditional wavefront shaping methods can be slow and computationally intensive, limiting their use in dynamic environments.
    • Genetic Algorithms (GAs) offer a powerful optimization approach but require acceleration for real-time applications.

    Purpose of the Study:

    • To develop an accelerated Genetic Algorithm (GA) system for rapid light focusing through scattering media.
    • To enhance the convergence speed and efficiency of GA-based wavefront shaping.
    • To demonstrate hardware-level acceleration using field-programmable gate arrays (FPGAs).

    Main Methods:

    • Developed an accelerated GA by optimizing the mutation rate decay ratio for faster convergence.
    • Defined a convergence-efficiency function to balance processing time and focal spot quality.
    • Implemented the accelerated GA on a field-programmable gate array (FPGA) for hardware acceleration.

    Main Results:

    • The enhanced decay ratio of the mutation rate significantly accelerated GA convergence.
    • The FPGA-based GA achieved light focusing through scattering media in seconds, 150 times faster than PC-based GAs.
    • The system demonstrated the potential for millisecond-level processing with advanced FPGA chips.

    Conclusions:

    • The accelerated GA system provides a highly efficient method for light focusing in scattering media.
    • FPGA implementation enables real-time wavefront shaping, adaptable to dynamic scattering environments.
    • This approach shows significant potential for applications in biological materials and advanced optical systems.
