Improving the quality of wavefront shaping (WFS) is a major problem of anti-scattering optical information transmission in the perturbation environment. To tackle this issue, we propose a simple and robust method, named Point Guard algorithm (PGA), to manipulate the optical interference by encoding the digital micromirror device (DMD). The PGA method is inspired by the movement strategies of Point Guard (PG) in professional basketball association. Compared with the most popular method genetic algorithm (GA), the proposed PGA method has a stronger anti-perturbation capacity. In the experiment, the scattering medium consists of ground glass and polystyrene microspheres (PS) suspended in deionized water, and the movement of microspheres is used to cause a perturbation. It is found that PGA still has a better modulation quality when the suspension is too thick to see the ballistic light. PGA puts a new perspective in applications such as optogenetics and biomedical imaging in complex environment.
