Focusing light through random scattering media by four-element division algorithm
چکیده انگلیسی


- A novel phase optimization approach to focus light through scattering media is proposed.
- This approach aims to improve the converging speed and susceptibility.
- The mechanism relies on constructive interference of all phase modulated elements.

The focusing of light through random scattering materials using wavefront shaping is studied in detail. We propose a newfangled approach namely four-element division algorithm to improve the average convergence rate and signal-to-noise ratio of focusing. Using 4096 independently controlled segments of light, the intensity at the target is 72 times enhanced over the original intensity at the same position. The four-element division algorithm and existing phase control algorithms of focusing through scattering media are compared by both of the numerical simulation and the experiment. It is found that four-element division algorithm is particularly advantageous to improve the average convergence rate of focusing.
