The application discloses a wavefront shaping system and method based on spatial division multiplexing. After the light beam emitted by a laser light source is expanded, modulated by a spatial light modulator, and passed through a rotating mask and a series of optical systems, the light beam is collected by a photoelectric detector. The laser light source enters the spatial light modulator. In a refresh cycle of the spatial light modulator, the rotating mask is rotated. For the sub-regions turned into the light path, the wavefront of the light beam is modulated by the modulation regions corresponding to the sub-regions. Finally, the wavefront is collected by the photoelectric detector. Then, a control unit processes four groups of signals obtained by using a wavefront shaping algorithm to obtain four groups of preliminary correction wavefront parameters. The rotating mask is removed, and the wavefronts of the four groups of correction wavefronts are matched to obtain a final correction wavefront signal. The application can realize accurate focusing of light after the light transmits through a scattering medium, and can realize higher light intensity gain under the same correction time.
